There once was a time in history that there actually were cams that were too large to be using on the streets. Not that you couldn't use them, but your car would be a dog. Today, not so much! Today we have tech that makes it possible to drive around with 5 second quarter mile machines on the road as if they were yesteryears hotrods! If you don't put the right tech together, then you can still have too large of a cam for your combo, but that's all on you. Honestly though, that cam is kind of a middle run cam. A big cam would be idling at 2000 rpm, and run up into the 7500+ rpm range. Nice build though, looks cool, sounds nice!! P.S. That steering wheel has amazing texture! lol
Thanks, I appreciate your honest words. I feel the same way. With the right tech and tuning, almost any camshaft can be streetable. That steering wheel does have an awesome texture!!! 😆 I really need to work on my camera skills. Thanks for watching!!!
@bowhite1293 I really wish we had e85 around here. Closest pump is 1hr from the house. Best we got is 91 so I have to add boostane or vp maddative. If not this thing will knock like crazy.
I have a 254/260 solid roller in my 388 Stroker 10.8-1 ETEC 200 heads 3800PTC TH350. After 15 years a lifter took a dump last week and this is the cam im going to replace it with when I freshen it up next week. Done got old and I don’t like running valves as much as I use to. I’m hoping I don’t lose to much go.
That tach you have fits perfectly in the center hole of your dash. I cut the clear lens of the cluster so the tach slipped in, on my '71. The outer lip of the tach will catch the black part of the cluster. The look was pretty clean.
Personally I love that truck and the way it runs. I don't think the cam is too big. I run a big cam in my bigblock 55. It cruises at about 2700 at 70 and I'm okay with that. Seems like the sweet spot for my engine. Early 70s 400 turbo and 373s.
Thanks!! It really does seem like a decent, streetable combo. So many people have told me that it's too much cam for the street or too much for a pickup. I really think it drives nice around town, gets 12ish mpg on the freeway at 80ish mph and will blow the tires off at will. What more could a guy want. Smiles per miles!!!
Howsrds cams are magic, it seems to have great drivability and nice power. my combo on paper should be not so hot with drivability but it works great. I have mild 9:1 355 in a 92 c1500 with old big valve/ ported 993s, original torker open pleanum intake with a 2" spacer and a no where as big howards 112031-08, 3.08 gears, it had monster 700r4 with 2500 stall and it ran great, good low end strong mid an decent top end and really lumpy idle long tubes through dual 3" axl dumps (just for sound), eventually the trans blew up and original stock tans and converter went back in and still runs just fine but slups under power. But at idle you can whack the throttle and roars to life the lighting up the tires and keeps it up for wuite aways its would smoke my stock 5.0 95 mustang gt thats not bad for that type of set up it should be a total pooch off idle.
@@jdbas71 the only other cam that ran surprisingly good was a lunati bracket master 2 but from now on if I buy a cam it's howards, David vizard the top end guru says if go flat tappit howards is the only safe brand, so that says something if a guy like him swears by them.
Your right. If David Vizard recommends something it holds some value. I had a lunati 268 voodoo that ran pretty darn good too. I tried the lunati bootlegger and wiped 8 lobes out in 200 miles
That is a healthy cam for the street. I have a 242/248 @ .050, .585 in a 427 sbc in a 73 corvette, manual transmission. I wouldn't go any bigger personally. It is already scary as hell:-)
Your 383 seems to be very street friendly, Idles nice etc, My 383 likes to idle around 1300rpm and has that old school rumble shake the car at the red light lol. I run the Howards 110635-10 which is a step below the cam you are running. It has treated me very good over the past 7 years.
This one was the same way idling high. I recurved the distributor where it idles at 18°advance and is all in around 2500 rpm at 36°. Made a world of difference on the streetability of this engine. Thanks for watching!!!!
Thanks!!!! I feel pretty content with this drivetrain. Kinda the best of both worlds. Will do massive burnouts and haul ass or cruise 80 down the interstate.
It is. Other than it's broke everything behind the engine so far.... THANKS FOR WATCHING!!!! More to come on this truck and my ol man's 69 firebird that's been off the rd since 91.
Well.... it's a mixed bunch. The 1st few weeks that this engine was in the truck it still had blown out glass packs and some long echo chambers on it. The wife said if I left the house she could hear it the entire time I was gone. So these magnaflows and 2½" pipe tamed it down some....
I love big Cams street applications, bought blueprint 509 BBC Cam lift 647 int 647 exhaust 248 deg int/254 exh, 112 CL behind tremec 5speed. Howard make awesome grinds and Durations on their Cam Sound Serious.
Same here. Your absolutely correct, howards cams seem like magic. This cam has way more duration and lift than a lunati 268 I ran, and it idles possibly smoother.
@jdbas71 that's a Ultradyne cam you have NOT a Howard's.... That cam profile is an Ultradyne from Harold Brookshires Landis Machine Howard's bought at the auction.... I have my own cam profile I got from Harold before he died... It's nasty asf !!! Pushes a 505 BBC very nicely 😎 .... The lil 268 lunati you spoke of us also an Ultradyne cam made for lunati under the Voodoo line... Harold's best cam he designed can still be bought from lunati as an off the shelf cam.... A flat tappet solid that will put a BBC 454 with 10.5:1 and proper heads in the 700/700 category.... Next is his .904 lifter profile for ASCA....
Thanks!!! Before the OD it was a great around town hot rod. The OD made it nice for hwy cruising. We've took it on several trips over an hr from the house. Needs a working ac next😆
Exactly 💯 plus this exhaust has made it so docile. Huge mufflers with an X pipe tamed it down to where it's very much a sleeper. I got on it next to a guy and he later laughed as he told me "I never would have expected that, you pulled up purring and next thing I knew it released demons and took off" 😆
Now that story make an old gearhead smile! Always loved a sleeper and the look of shock on some unsuspecting driver with more money than ability. @@jdbas71
Hard to hear in the video, once I got up to 70-80ish it had an awful growl coming from the diff. Pulled the cover and it's full of glitter. Looks like it was crushing the crush sleeve under power and the pinion preload was gone. I've got in it a few times. Rolled into it at 50ish and found the limit of a stock built th350. Fixed that and brought it up on the stall and floored it in the driveway. Exploded the front yoke. That's why is has the 4l80e, 3in shaft with 1350 yokes now lol. Currently on jackstands waiting on the ring and pinion to get here.
I've got a single pattern solid cam, 241/241 @50 on a 108 lobe centre with 550 lift in my oval port big block chev Holden HQ Monaro. 2800 stall, 3.5 gears 255/60/15 tyres. Great fun to drive daily down here in Australia ( when it aint raining )
Here's a question for some of you. The speedo in that truck goes to 100 as did my '69 GMC, how fast would you estimate my truck was running with my speedo all the way around and back up to 20 ? I have 2 other witnesses that it did as they were in the truck with me. It had a Saginaw 3 sd, 3.73 rear gears, and Mickey Thompson L60's on 15" rims. Everything was factory except the engine we built for it. You have a nice sounding and great running truck!
I'm guessing around 140 or so. That about the speed when my old 70 gmc started getting real light in the front end. My buddy yelled shut er down. Lol we were young then.
@@jdbas71 that’s what mine started doing and my friend, who was on the passenger side told me he thought it was time to slow down. The poor girl I was trying to impress was between us. I can’t say she was sitting next to me because she was halfway in the floor! She didn’t have anything else to say about her boyfriend’s Ford truck though! Lol! The thing is, I still had pedal left but I weren’t going to find top end! When the front end of your vehicle starts floating, it’ll get your attention real fast! Lol!
Wallace racing us all kinds of calculators. Of course me the speed one may be off because of aerodynamics and or weight. Also if you still have the truck, put the speedo AP on your phone and it will be very close to what you are actually driving. We’ve used it in the past.
I love how you have the idle set at 950-1000 rpm’s… it sounds great👍🏼 So many out there set their idle at 600 to exaggerate the lope in the cam. It sounds terrible, and reminds me of a tug boat.
Thanks I appreciate that!!! Even been alot of people comment that it don't lope that hard. Well..... it's got around 20° of timing at idle and idles around 1000rpm 😆
@@jdbas71 I pitted for my brother several years ago racing GA modifieds. We ran a 377 small block on alcohol with pretty aggressive cam and 8 into 1 exhaust. It idled at 1200 rpm and sounded similar to your truck. You’ve got a nice cam 👍🏼
All the people who make the comments about too much motor for the street are running Mopars the original slow cars . Or just plain old dumb and running a ford. GM #1 .
Thanks!!! It's nothing special, a junkyard 4l80e from a 06 express van with an eBay controller. The controller is the NCR80E. It hooks up with one hot wire and a switched ground for the lock-up converter. Converter is a PTC, it was actually specd to go behind 700ish hp turbo LS. That project ain't no where near completed so I used the trans in this truck.
Slow speed on the tack was about 1000 RPM’s. Idling under a grand. A 5 speed Tremec would be more fun. I would nix the automatic. Loose converters feel sloppy and excess noise to drive. At 225 degree or less cam would be better suited for the street in a not so light vehicle. Throttle response would be better too coming off a stop.
I agree smaller cams are way more street friendly in a heavy pickup and way easier to tune but.... As far as the auto, yeah a 5 speed would be more fun but not in this truck. Maybe one of the others. Out of the 5 67-72s I own, the is the only one without the third pedal.
It seems to be well mannered , and assuming you're running manual brakes. Curious to know what the vacuum is at idle. The more efficient the intake system is the lower the vacuum will be. What about heads, intake and Carb?
Still has power brakes on it. Only makes about 5" @ idle. Once cruising, the brakes are good for the first pump or two, but after that they get hard. When I first put it together, it had a single plane victor jr knock off. I put a performer rpm on it, and it seemed to pick up better street matters. It has a 750 brawler, mechanical secondary carb. The heads are cheap aluminum heads that look like a dart copy. I think they came from skip white performance.
I have 383 AFR CNC 210 heads 575 lift 255@50 pushing a 3800 car no driver ran 11.95 116 mph 1/4 mile shifting 6800 crossing at 6000rpm a little under geared for peak 1/4 mile.been street driving for 4 years no issues no maintance
Thanks!!! All in the tune-up. When I 1st got it running it idled like a dying pig. Was way rich, and wouldn't idle much under 1300rpm. Some timing curve adjustment and some carb tuning smoothed it out. It turned out to be a very friendly cruiser.
No such thing as too much cam, just means ya need more of everything else. I've ran 290@.050 .800 lift solid roller cams & 13-1 compression rowdy bigblocks that I drove to work everyday. All depends on how much ya can deal with. That truck appears pretty mild and totally drivable. Probably get 15-20mpg.
Point duly noted. You had me before you even turned around to go back to town. it sounded pretty docile from here. One thing though, I like to see the gauges not the foam on the steering wheel. LOL! Howard's has always had a pretty nice camshaft. that is still on the Salty side of street application though, nowhere near Peppery yet. Peppery is when it is just too heinous to drive on the street and it demands to be a Trailer Queen!....🤭. you knew that⚡️😝✌️
Thanks for watching!!!! I'll work on my camera skills 😆 in my defense there was a lot going on. I had a lit cigarette, steering wheel, manually shifting, and recording. 😆 🤣
@@jdbas71 🤯☝️also, no selfie stick...all in all good job. And very decent cam selection. I've had good results with Shnider's Racing Cams aggressive grind fools ya into thinking it's idling @ about 400, but the tach is actually bouncin between 1400 - 2600. (roughly) At 3200, its still slobberin' all over the place, but the fat lady's just showin' up, and ready to sing the high notes. Just...not on the street!🚫 oh yeah, NICE P/U! my cousin has a nice original '72 Cheyenne, same paint and trim....another decent selection. I already been buggin him, & he wont LS swap it. Edited... ✌️🍺🍺🍺🍺🍺🍺👍.... have a couple
Great video Thx , nothing like playing with a sbc , I have a 81 1500 an when i retired put an old circle track motor built when i was young an had energy , it's a 283 stroked to 354 at the time was 360 cubes an under cam lift rules motor , so limited to 445 lift , has more duration than your cam though an is flat tappet , bit more compression at 11.5 with ross pistons an 58 cc heads , only issues are with todays gas limited to 94 octane can't run as much timing as would like an of course no power brakes , been my daily driver for 11 years now .
Thanks!!! It just seems like every cam video on UA-cam is a sbc idling in the driveway. That little sbc sounds like a screamer!!! Have you tried good octane booster? I've had the best luck with VP maddative, the purple can. Actually smells like race fuel from the exhaust. Recently been using Boostane professional. Supposedly raises octane about the same but can mix more fuel/bottle.
@@jdbas71 Your right to many people build motors that won't daily drive or they can't tune them an they sit and problems start , their supposed to take you places lol an yep have tried probably 4/5 octane boosters they work to a point but they put a coating on the plugs an that causes issues so i gave up an dialed the timing back , had 72 cc heads on it but cracked a valve couple years ago an did these up so probably going to fix those put them back on , these probably running about 34 degrees all in an it's just on the brink of being ok think with todays gas anything over about 10 1/2 compression is probably a bit much really
I was wondering how you shifted that 4l80 then i saw you manually shift it so no auto shift thats ehat i wondered no tps to give the signal no computer at all for the trans why not a turbo 400 w a gear vendors idk just curious
@GlennManchester main reason was cost. I picked this trans up for $900 with a brand new ptc converter. Had to change the valve body because it only had 1st and second. So with the trans, controller, converter, and new 3" drives shaft, i was only into it for under 2k. Later I might put in a controller like a US Shift.
Driveable, and driveability on a daily basis are not the same. It's all about matching peak torque production to rpm's you will see most often. That is determined by many factors. This build is counter productive. 383 build = lower end torque production, od trans, tall gears ike LOW end torque. Driving around town LOVES low end torque. Cam that starts coming on at 2500? Sounds great but for a daily that lope means your mileage suffers for the sound. Throw in a cam suited for low end torque and then go ahead and advance it 4 degrees and you will get way better mileage, and you will have a stump puller!
This engine was originally built to go in a 2nd gen camaro. I think the cam company recommended this cam to bleed off more cylinder pressure to be able to keep it in the pump gas range. The engine is 11.2:1 compression. This truck has 3.73 gears. Is it suitable for "daily driving"? I had a goodwrench 350/th350 in this truck before and averaged 10mpg on a 500 mile trip. This 383 makes probably more than double the hp and averages 12.5mpg. It even gets better average mileage than my other 71c10 that has a stock rebuilt 350/4speed and 3.42 gears.
For daily driving, this converter feels great. I feel a looser converter would help out of the hole a little bit. Too loose, and it could just blow through the converter on the big end. Thanks for watching!!!!
That cam is tiny! Any cam that idles below 1500 rpm with enough stall or manual trans works perfectly. One of my street cars idle @ 1900 lope up to 2600 & all hell brakes loose @ 5500 pulls past 7000 yea I have 4.56 gears with a Jericho trans but i never said it was a "daily" driver.
Not criticizing but it sounds kinda stock to me. My 427 ford fe has a lot more chop to it, and it only has a .600 lift 300degree 106 center line cam. What is your compression ratio?, maybe that's why it sounds so much different than mine.
Ah no criticism taken. Its 11.2:1 compression. Scat crank/rods, wiseco forged flat tops, 200cc intake heads w/2.02/1.60 valves. Cam is 247/253@.50 .608/.612 lift (1.6 rockers) on a 106 centerline. "Chop" is all in the tune up. I've recurved the distributor so it has alot of initial advance with a short advance curve. Bought as tight of a curve as I can get without just locking it out. I tuned the four corner idle adjustment with a vacuum gauge to reach the highest vacuum at idle in gear. (About 5.5" of vacuum) My tune up is strictly for smoothest idle/ throttle response over chop. When I first got this thing running it wouldn't idle below about 1300rpm and idled like a dying pig. Recurving the distributor and excessively playing with the carb got it to idle nicely around 900-1000 with GREAT throttle response off idle. It also has an X pipe in the exhaust which really changed the sound, not only at idle but all the way through the rpm range.
And to think, when I got this truck 11ish yrs ago, my intention was to part it out to fix my grandpa's GMC. It was faded real bad as it had sat for over 10 yrs. I washed it and waxed it, and the color grew on me.
Haven't towed a trailer with this setup but did haul 1600# of laundry soap down the interstate at 80mph. I just locked the converter up when I got up to cruising speed. Felt like it wasn't even in there.
It can't be that big if you set the red line @ 5,000 rpm. Yes I know it's a 383 but a 2019 Charger 392 is larger but redline @ 6,000 rpm. What gear ratio?
The cam company says 28-6600 rpm. That little red slider gets moved around all the time as I don't have a working speedometer at the moment. I have a rev limiter set around 6200.
Silly question but what’s the fuel mileage like with a big hogging ass cam like that? I feel like what’s stopping most people from running a big cam is the idle quality and the fuel economy, I’m looking to ls swap a ranger for a fun daily type build but I’m worried sick that if I put a cam with 220+ on the intake lobe it’s gonna drop fuel economy hard and I really don’t need a daily that gets 5 miles per gallon
That's a great question! On the interstate, I've averaged about 12.5mpg between 80-85 mph. My old Goodwrench 350 without overdrive averaged 10mpg at 60-65mph. Totally shocked the crap out of me. I've calculated mileage 3 times filling up and driving about 70 miles back to town, then topping off again. It would probably do better but there are 3 or 4spots of road construction on the way home and I like the way it will just walk TF away from traffic on the interstate. I would like to get an air/fuel ratio gauge to be able to dial in the fuel mileage.
@johnpopoff7950 I can't believe this stroker gets better mileage than the Goodwrench. Maybe it's the overdrive, maybe it's because it makes double the power. Either way, 3mpg or 13mpg I'm still gonna drive it.
Ive got a 383 stroker in my shorty chevy van. 700r4 trans its getting 373 gears soon. I feel my stock/original converter is too tight at 1500rpm. Like the motor is fighting it at idle speed. Id like a 2000ish converter. Im not racing. Does that sound about right? What is the stall speed on this converter in the video?
Behind this 383 it stalls about 24-2500rpm. The converter was built originally built for a turbocharged 5.3 ls. Behind 700ish hp, it should stall about 3700rpm. The cam company recommends a 3500 with this camshaft. This converter is just a little tight for this engine. I had a 2400 b&m behind the old goodwrench engine & loved it. What's your cam specs? That will more closely determine stall speed.
@kennydemartini2169 I drove a heat & air van for a guy yrs ago that had a 4.3. It did seem to stall weirdly high. It didn't seem like a good match to a 4.3 at all. That thing was gutless as they come. Would be way better with a v8 in front of it.
My thoughts also.My factory RA/IV cam had more pop than this at its 1050rpm spec.Tried to lower the idle down once,and when it hit 650rpm it backfired and died.It was not meant to be coupled with a stock M40 auto,so I had to set the idle up to 2000rpm to drive it home from my dad’s garage.In gear it would drop to 750rpm,but would lurch (pulsate)with the front end moving up and down.It was lurching like this when a cop pulled up next to me at a light.He lit me up,then told me it was not streetable,if he sees it again he will write me up.Had to put a stall in it for drivability.This 70 crate engine was dropped into my 1964 GTO.
@babaoreally8220 this cam is around 250° and .600 lift. It's tuned up with 20° of timing at idle and a short curve. I gave it that much timing to help out the idle quality. When I first got it running the dizzy had something like a 26° curve. With 10° initial this engine would idle like a dying pig.
@@jdbas71 agreed,10* for a hot cam is way low.The way they are measuring these durations up the ramp now is difficult for me to convert to the classical spec.I love to hear those thumpers in a pick-up truck.There’s one (mid 70’s) next door that really pops,and I wander over to take it all in.Sounds like someone banging a bass drum when sitting in the living room.The factory cam in mine was a heavily double sprung hydraulic,but you could hear the valves snap shut,like a solid lifter.The construction of the lifter was such that it acted like a solid lifter as rpm’s got higher.The 308/320* duration and .530 net lift was the most radical of GM’s factory engines.
@@jdbas71 the flex lines need slicker grease but the dang square extension wears down. The truck looks awesome in the original paint though. Hard to justify fixing it up in new. Still looks great!
@benhudman7911 and to think..... 11ish yrs ago, when I found it parked non running, my initial intention was to part it out to fix my grandpa's gmc. I got the original engine running and washed and waxed it. Went all downhill from there. There's no way I could part it out then. It just became part of the collection lol.
I worked at Wolf Creek Nuclear Creek power plant for about 9 months in the mid 80s I liked it out there but had to get back to Carolina. Great sounding truck. You should be proud of yourself. You did a great job.@@jdbas71
Want to know if u think it's big cam who would have read line at 5 grand. Have a Monte big block 680 lift drive every were 7800 all the time Cruz Town all day
😆 I had a grip of people tell me i over cammed my small block for the street. 😆 I laughed because they probably tried it and dropped thier stock hei in, set the timing to factory spec and it ran like shit. If the tune is right, ya can get some really radical engines to have really great street manners. In all actuality, the redine is just there. I slide that thing around all the time because I don't have a working speedometer at the moment. Set it at my intended hwy speed and keep it somewhere close to that. It has a rev limiter so I ain't to worried about a "redline". A guy can rev an engine to 8k all day but really pointless if it peaks hp around 6k.
Jesus, it's so flat out there you could watch your dog run away for two days.

Thats less lope than my old 383 Stroker S10 had and it was fully streetable. Your exhaust, when accelerating, sounds amazing. Beautiful ride!
Thanks!!! It's got a lot of initial advance which really helped smooth out the idle some.
Exhaust is 2½" Magnaflow knockoffs with an X pipe.
I like how my 68 Camaro 396 pulls with a 580 lift 300 duration, gets lots of looks pulling into car shows too, nice truck keep the videos coming

There once was a time in history that there actually were cams that were too large to be using on the streets. Not that you couldn't use them, but your car would be a dog.
Today, not so much! Today we have tech that makes it possible to drive around with 5 second quarter mile machines on the road as if they were yesteryears hotrods! If you don't put the right tech together, then you can still have too large of a cam for your combo, but that's all on you.
Honestly though, that cam is kind of a middle run cam. A big cam would be idling at 2000 rpm, and run up into the 7500+ rpm range. Nice build though, looks cool, sounds nice!!
P.S. That steering wheel has amazing texture! lol
Thanks, I appreciate your honest words. I feel the same way. With the right tech and tuning, almost any camshaft can be streetable.
That steering wheel does have an awesome texture!!! 😆 I really need to work on my camera skills. Thanks for watching!!!
Awesome. I daily'd a 243/255 on 12:1 and a +5000 8" stall for almost 3 years. Loved it
12:1 What did you run for fuel and timing?
Flexfuel
12* on 93 and 16* on E. I may be wrong on that. Don't exactly remember.
@bowhite1293 I really wish we had e85 around here. Closest pump is 1hr from the house. Best we got is 91 so I have to add boostane or vp maddative. If not this thing will knock like crazy.
It's not common here. 3 stores in my county have it. Closest is 20 minutes.
Let us know how many miles you get from your lifters wt 750lbs of spring
Sounds just right to me. Great sound.
Thanks!!!!
I have a 254/260 solid roller in my 388 Stroker 10.8-1 ETEC 200 heads 3800PTC TH350. After 15 years a lifter took a dump last week and this is the cam im going to replace it with when I freshen it up next week. Done got old and I don’t like running valves as much as I use to. I’m hoping I don’t lose to much go.
That tach you have fits perfectly in the center hole of your dash. I cut the clear lens of the cluster so the tach slipped in, on my '71. The outer lip of the tach will catch the black part of the cluster. The look was pretty clean.
I've thought about doing that. I have an extra lens from another truck I could use as a donor.
Personally I love that truck and the way it runs. I don't think the cam is too big. I run a big cam in my bigblock 55. It cruises at about 2700 at 70 and I'm okay with that. Seems like the sweet spot for my engine. Early 70s 400 turbo and 373s.
Thanks!! It really does seem like a decent, streetable combo. So many people have told me that it's too much cam for the street or too much for a pickup. I really think it drives nice around town, gets 12ish mpg on the freeway at 80ish mph and will blow the tires off at will. What more could a guy want. Smiles per miles!!!
@@jdbas71 exactly!!!
If someone tells you that a cam is too big for the street they do not know how to build a engine or understand how to make a combo work.
That's what I said. Probably total lack of tuning knowledge because the tune up specs on the fender sticker ain't gonna make the cut.
Wish my cab was that guit.
Awesome truck
Thanks. New dash pad and seat cover made a world of difference.
I miss my 71 short y so it was a lot more of a handful. your truck is awesome brother
That's sweet, something to be proud of.
Thanks and thanks for watching!!!!
Howsrds cams are magic, it seems to have great drivability and nice power. my combo on paper should be not so hot with drivability but it works great. I have mild 9:1 355 in a 92 c1500 with old big valve/ ported 993s, original torker open pleanum intake with a 2" spacer and a no where as big howards 112031-08, 3.08 gears, it had monster 700r4 with 2500 stall and it ran great, good low end strong mid an decent top end and really lumpy idle long tubes through dual 3" axl dumps (just for sound), eventually the trans blew up and original stock tans and converter went back in and still runs just fine but slups under power. But at idle you can whack the throttle and roars to life the lighting up the tires and keeps it up for wuite aways its would smoke my stock 5.0 95 mustang gt thats not bad for that type of set up it should be a total pooch off idle.
Yes, they are. I never would have thought this much cam would be this well mannered, especially with the converter that's in it.
@@jdbas71 the only other cam that ran surprisingly good was a lunati bracket master 2 but from now on if I buy a cam it's howards, David vizard the top end guru says if go flat tappit howards is the only safe brand, so that says something if a guy like him swears by them.
Your right. If David Vizard recommends something it holds some value. I had a lunati 268 voodoo that ran pretty darn good too. I tried the lunati bootlegger and wiped 8 lobes out in 200 miles
Very sharp and great sounding and running truck!!
THANKS!!!
Never too much cam, just need more convertor, more gear and a heavier foot
Exactly!!!! Overdrive with lock up was a complete game changer.
Too much cam means how often do you wanna be changing lifters!
Sweet C10 love the two tone, don't change a thing.
@@corysather6640 THANKS CORY!!!!
Truck sounds great. Set-up works. Be proud of it.
Works pretty good. Thanks!!!
Never too much cam just not enough motor
ABSOLUTELY CORRECT!!!!
That is a healthy cam for the street. I have a 242/248 @ .050, .585 in a 427 sbc in a 73 corvette, manual transmission. I wouldn't go any bigger personally. It is already scary as hell:-)
Beautiful Truck and such a classic color
Thanks!!!
Nice strong build sounds awesome !!!!!!!
Thanks!!!!
Your 383 seems to be very street friendly, Idles nice etc, My 383 likes to idle around 1300rpm and has that old school rumble shake the car at the red light lol. I run the Howards 110635-10 which is a step below the cam you are running. It has treated me very good over the past 7 years.
This one was the same way idling high. I recurved the distributor where it idles at 18°advance and is all in around 2500 rpm at 36°. Made a world of difference on the streetability of this engine. Thanks for watching!!!!
Yup she's a keeper; just like it is. nice job
Thanks!!!! I feel pretty content with this drivetrain. Kinda the best of both worlds. Will do massive burnouts and haul ass or cruise 80 down the interstate.

It is. Other than it's broke everything behind the engine so far.... THANKS FOR WATCHING!!!! More to come on this truck and my ol man's 69 firebird that's been off the rd since 91.
cool I like 383 strokers my friend had one back in the seventies in his 67 camaro. It was a ripper. It sure looks like Kansas there. Or Oklahoma.
Kansas 😆

Well.... it's a mixed bunch. The 1st few weeks that this engine was in the truck it still had blown out glass packs and some long echo chambers on it. The wife said if I left the house she could hear it the entire time I was gone. So these magnaflows and 2½" pipe tamed it down some....
I'd love him 😅
Joe Sherman once said An engine can take more cam than you think
Joe was right. A little tuning and a lockup converter can make "almost" anything streetable.
@@jdbas71 3800-4000 stall and some 4.30s will do the trick with this bad boy 😅😂

I love big Cams street applications, bought blueprint 509 BBC Cam lift 647 int 647 exhaust 248 deg int/254 exh, 112 CL behind tremec 5speed. Howard make awesome grinds and Durations on their Cam Sound Serious.
Same here. Your absolutely correct, howards cams seem like magic. This cam has way more duration and lift than a lunati 268 I ran, and it idles possibly smoother.
@jdbas71 that's a Ultradyne cam you have NOT a Howard's.... That cam profile is an Ultradyne from Harold Brookshires Landis Machine Howard's bought at the auction.... I have my own cam profile I got from Harold before he died... It's nasty asf !!! Pushes a 505 BBC very nicely 😎 .... The lil 268 lunati you spoke of us also an Ultradyne cam made for lunati under the Voodoo line...
Harold's best cam he designed can still be bought from lunati as an off the shelf cam.... A flat tappet solid that will put a BBC 454 with 10.5:1 and proper heads in the 700/700 category.... Next is his .904 lifter profile for ASCA....
That is a great sounding engine at that speed with OD.
Thanks!!! Before the OD it was a great around town hot rod. The OD made it nice for hwy cruising. We've took it on several trips over an hr from the house. Needs a working ac next😆

@@jdbas71.... Should have used a th400 w/ gearvendors behind it... 6spd auto 😎😁😁😁😁
People forget that high compression counteracts the low vacuum of a big cam. My 383 makes 20inhg at idle with a howards 111655 cam.
Thats awesome, nice ride 👍
Thanks!!!!
Most won't match converter or other components then whine and pout and blame manufacturers for their own lack of research and planning
Excellent explanation!!
It starts, idles and drives without stalling off idle. Then when warm it purrs around town! What's not to like?
Exactly 💯 plus this exhaust has made it so docile. Huge mufflers with an X pipe tamed it down to where it's very much a sleeper. I got on it next to a guy and he later laughed as he told me "I never would have expected that, you pulled up purring and next thing I knew it released demons and took off" 😆
Now that story make an old gearhead smile! Always loved a sleeper and the look of shock on some unsuspecting driver with more money than ability. @@jdbas71

I runn a 355 with a Procharger. Isky solid .507 lift, 3600 converter. Drive it everywhere.
I figured he'd show how much power it really has the guys like my grandpa
Hard to hear in the video, once I got up to 70-80ish it had an awful growl coming from the diff. Pulled the cover and it's full of glitter. Looks like it was crushing the crush sleeve under power and the pinion preload was gone. I've got in it a few times. Rolled into it at 50ish and found the limit of a stock built th350. Fixed that and brought it up on the stall and floored it in the driveway. Exploded the front yoke. That's why is has the 4l80e, 3in shaft with 1350 yokes now lol.

Here's a question for some of you. The speedo in that truck goes to 100 as did my '69 GMC, how fast would you estimate my truck was running with my speedo all the way around and back up to 20 ? I have 2 other witnesses that it did as they were in the truck with me. It had a Saginaw 3 sd, 3.73 rear gears, and Mickey Thompson L60's on 15" rims. Everything was factory except the engine we built for it. You have a nice sounding and great running truck!
I'm guessing around 140 or so. That about the speed when my old 70 gmc started getting real light in the front end. My buddy yelled shut er down. Lol we were young then.
@@jdbas71 that’s what mine started doing and my friend, who was on the passenger side told me he thought it was time to slow down. The poor girl I was trying to impress was between us. I can’t say she was sitting next to me because she was halfway in the floor! She didn’t have anything else to say about her boyfriend’s Ford truck though! Lol! The thing is, I still had pedal left but I weren’t going to find top end! When the front end of your vehicle starts floating, it’ll get your attention real fast! Lol!
Wallace racing us all kinds of calculators. Of course me the speed one may be off because of aerodynamics and or weight. Also if you still have the truck, put the speedo AP on your phone and it will be very close to what you are actually driving. We’ve used it in the past.
@@MikeFL2TX I use a speed app all the time. They work great.
I don't know, but I can tell you this; at 130 miles an hour telephone poles DO start to look like a picket fence, & @ 160 they're just strobing!
That's a great sound...
Thank you. Runs great. 😊
@@DennisL-n6i Thanks
I love how you have the idle set at 950-1000 rpm’s… it sounds great👍🏼 So many out there set their idle at 600 to exaggerate the lope in the cam. It sounds terrible, and reminds me of a tug boat.
Thanks I appreciate that!!! Even been alot of people comment that it don't lope that hard. Well..... it's got around 20° of timing at idle and idles around 1000rpm 😆
@@jdbas71 I pitted for my brother several years ago racing GA modifieds. We ran a 377 small block on alcohol with pretty aggressive cam and 8 into 1 exhaust. It idled at 1200 rpm and sounded similar to your truck. You’ve got a nice cam 👍🏼
All the people who make the comments about too much motor for the street are running Mopars the original slow cars . Or just plain old dumb and running a ford. GM #1 .
Haha....I run a Mopar but built a few chevy trucks....76 and 79
Haa your the dumb one. I own both. Your still young n dumb because your still in biased mind frame thar you know it all.

In the meantime there are GPS-based speed indicator apps that work on cell phones and tablets.
@@OOICU812 I use one alot
Awesome truck. I dig it. Man does that thing shift nice
Thanks!!! It's nothing special, a junkyard 4l80e from a 06 express van with an eBay controller. The controller is the NCR80E. It hooks up with one hot wire and a switched ground for the lock-up converter. Converter is a PTC, it was actually specd to go behind 700ish hp turbo LS. That project ain't no where near completed so I used the trans in this truck.
Slow speed on the tack was about 1000 RPM’s. Idling under a grand. A 5 speed Tremec would be more fun. I would nix the automatic. Loose converters feel sloppy and excess noise to drive. At 225 degree or less cam would be better suited for the street in a not so light vehicle. Throttle response would be better too coming off a stop.
I agree smaller cams are way more street friendly in a heavy pickup and way easier to tune but.... As far as the auto, yeah a 5 speed would be more fun but not in this truck. Maybe one of the others. Out of the 5 67-72s I own, the is the only one without the third pedal.
It seems to be well mannered , and assuming you're running manual brakes. Curious to know what the vacuum is at idle. The more efficient the intake system is the lower the vacuum will be. What about heads, intake and Carb?
Still has power brakes on it. Only makes about 5" @ idle. Once cruising, the brakes are good for the first pump or two, but after that they get hard. When I first put it together, it had a single plane victor jr knock off. I put a performer rpm on it, and it seemed to pick up better street matters. It has a 750 brawler, mechanical secondary carb. The heads are cheap aluminum heads that look like a dart copy. I think they came from skip white performance.
That firing order at idle is sweeeeeeet mutherfvck'n music!

Sounds pretty smooth
Thanks!!! All in the tune-up. When I 1st got it running it idled like a dying pig. Was way rich, and wouldn't idle much under 1300rpm. Some timing curve adjustment and some carb tuning smoothed it out. It turned out to be a very friendly cruiser.
@@jdbas71 I'm an old motorcycle tuner, and have tuned a many Rochester quad jets, sounds like you have that one right

No such thing as too much cam, just means ya need more of everything else. I've ran 290@.050 .800 lift solid roller cams & 13-1 compression rowdy bigblocks that I drove to work everyday. All depends on how much ya can deal with. That truck appears pretty mild and totally drivable. Probably get 15-20mpg.

You drive to work with race gas everyday? That gets EXPENSIVE. I've been there, and STILL am there...
Point duly noted. You had me before you even turned around to go back to town. it sounded pretty docile from here. One thing though, I like to see the gauges not the foam on the steering wheel. LOL!

Great video Thx , nothing like playing with a sbc , I have a 81 1500 an when i retired put an old circle track motor built when i was young an had energy , it's a 283 stroked to 354 at the time was 360 cubes an under cam lift rules motor , so limited to 445 lift , has more duration than your cam though an is flat tappet , bit more compression at 11.5 with ross pistons an 58 cc heads , only issues are with todays gas limited to 94 octane can't run as much timing as would like an of course no power brakes , been my daily driver for 11 years now .
Thanks!!! It just seems like every cam video on UA-cam is a sbc idling in the driveway. That little sbc sounds like a screamer!!! Have you tried good octane booster? I've had the best luck with VP maddative, the purple can. Actually smells like race fuel from the exhaust. Recently been using Boostane professional. Supposedly raises octane about the same but can mix more fuel/bottle.
@@jdbas71 Your right to many people build motors that won't daily drive or they can't tune them an they sit and problems start , their supposed to take you places lol an yep have tried probably 4/5 octane boosters they work to a point but they put a coating on the plugs an that causes issues so i gave up an dialed the timing back , had 72 cc heads on it but cracked a valve couple years ago an did these up so probably going to fix those put them back on , these probably running about 34 degrees all in an it's just on the brink of being ok think with todays gas anything over about 10 1/2 compression is probably a bit much really
Thats a nice street cam
I was wondering how you shifted that 4l80 then i saw you manually shift it so no auto shift thats ehat i wondered no tps to give the signal no computer at all for the trans why not a turbo 400 w a gear vendors idk just curious
@GlennManchester main reason was cost. I picked this trans up for $900 with a brand new ptc converter. Had to change the valve body because it only had 1st and second. So with the trans, controller, converter, and new 3" drives shaft, i was only into it for under 2k. Later I might put in a controller like a US Shift.
@jdbas71 I know nothing is cheap anymore lol
Driveable, and driveability on a daily basis are not the same. It's all about matching peak torque production to rpm's you will see most often. That is determined by many factors. This build is counter productive. 383 build = lower end torque production, od trans, tall gears ike LOW end torque. Driving around town LOVES low end torque. Cam that starts coming on at 2500? Sounds great but for a daily that lope means your mileage suffers for the sound. Throw in a cam suited for low end torque and then go ahead and advance it 4 degrees and you will get way better mileage, and you will have a stump puller!
This engine was originally built to go in a 2nd gen camaro. I think the cam company recommended this cam to bleed off more cylinder pressure to be able to keep it in the pump gas range. The engine is 11.2:1 compression. This truck has 3.73 gears. Is it suitable for "daily driving"? I had a goodwrench 350/th350 in this truck before and averaged 10mpg on a 500 mile trip. This 383 makes probably more than double the hp and averages 12.5mpg. It even gets better average mileage than my other 71c10 that has a stock rebuilt 350/4speed and 3.42 gears.
Again counterproductive. Any time this bleed cylinder pressure tactic is used, power is left on the table. Imho... Wrong cam..
Sounds streetable to me. Where’s timing on it? What’s the state emissions on it?
We don't have any state emissions checks. On this fuel, the timing is 18° at idle and 36° total. All in by about 2500rpm
The more radical the cam, the more stall you need on the torque converter. Standard transmission, not a problem.
For daily driving, this converter feels great. I feel a looser converter would help out of the hole a little bit. Too loose, and it could just blow through the converter on the big end. Thanks for watching!!!!
I had a 570 lift in a 350 3500stall sounded like this chops perfect
I'd drive it daily...sounds mean af dude and it's manageable..
That cam is tiny!
Any cam that idles below 1500 rpm with enough stall or manual trans works perfectly. One of my street cars idle @ 1900 lope up to 2600 & all hell brakes loose @ 5500 pulls past 7000 yea I have 4.56 gears with a Jericho trans but i never said it was a "daily" driver.
How often do you replace springs & lifters?
Just found your channel, Cool truck.
Thanks!!! Yours looks amazing to!!
Low gear in the rear. My 342 rear 350 700r4 at 65 is 1900!
Yeah. 3.73 on a 275/60/15
Not criticizing but it sounds kinda stock to me. My 427 ford fe has a lot more chop to it, and it only has a .600 lift 300degree 106 center line cam. What is your compression ratio?, maybe that's why it sounds so much different than mine.
Ah no criticism taken. Its 11.2:1 compression. Scat crank/rods, wiseco forged flat tops, 200cc intake heads w/2.02/1.60 valves. Cam is 247/253@.50 .608/.612 lift (1.6 rockers) on a 106 centerline. "Chop" is all in the tune up. I've recurved the distributor so it has alot of initial advance with a short advance curve. Bought as tight of a curve as I can get without just locking it out. I tuned the four corner idle adjustment with a vacuum gauge to reach the highest vacuum at idle in gear. (About 5.5" of vacuum) My tune up is strictly for smoothest idle/ throttle response over chop. When I first got this thing running it wouldn't idle below about 1300rpm and idled like a dying pig. Recurving the distributor and excessively playing with the carb got it to idle nicely around 900-1000 with GREAT throttle response off idle. It also has an X pipe in the exhaust which really changed the sound, not only at idle but all the way through the rpm range.
@@jdbas71 nice! That explains it, thanks for the reply.

same color and dash as a '73 blazer I had
And to think, when I got this truck 11ish yrs ago, my intention was to part it out to fix my grandpa's GMC. It was faded real bad as it had sat for over 10 yrs. I washed it and waxed it, and the color grew on me.
How does it do with towing? Lock up the converter early to prevent slipping?
Haven't towed a trailer with this setup but did haul 1600# of laundry soap down the interstate at 80mph. I just locked the converter up when I got up to cruising speed. Felt like it wasn't even in there.
It can't be that big if you set the red line @ 5,000 rpm. Yes I know it's a 383 but a 2019 Charger 392 is larger but redline @ 6,000 rpm. What gear ratio?
The cam company says 28-6600 rpm. That little red slider gets moved around all the time as I don't have a working speedometer at the moment. I have a rev limiter set around 6200.
@@jdbas71 I'm sorry. It does sound like it will cut a rug.

Theres many limiting factors to safe rpm.

Lol, back in town, streets are empty 😂 wish I lived there 😢
Small town living is where it's at. I don't mind going to the city if we have to but I'm ready to leave after a few hrs.
sounds good. i've heard bigger loops.
I almost think my 268 voodoo cam in my ol 355 loped harder.
Silly question but what’s the fuel mileage like with a big hogging ass cam like that? I feel like what’s stopping most people from running a big cam is the idle quality and the fuel economy, I’m looking to ls swap a ranger for a fun daily type build but I’m worried sick that if I put a cam with 220+ on the intake lobe it’s gonna drop fuel economy hard and I really don’t need a daily that gets 5 miles per gallon
That's a great question! On the interstate, I've averaged about 12.5mpg between 80-85 mph. My old Goodwrench 350 without overdrive averaged 10mpg at 60-65mph. Totally shocked the crap out of me. I've calculated mileage 3 times filling up and driving about 70 miles back to town, then topping off again. It would probably do better but there are 3 or 4spots of road construction on the way home and I like the way it will just walk TF away from traffic on the interstate.
I would like to get an air/fuel ratio gauge to be able to dial in the fuel mileage.
Who cares about gas mileage with that beast.
@johnpopoff7950 I can't believe this stroker gets better mileage than the Goodwrench. Maybe it's the overdrive, maybe it's because it makes double the power. Either way, 3mpg or 13mpg I'm still gonna drive it.
Just put a Howard's cam in my mpala runs great
Wow. Nice cam whats the basick rpm range great sound
@donaldcochrane3283 Howards says rpm range is 2800 - 6400.
Very Nice!!

Thanks!!! Short beds are nice but very pricey. I've got 4 complete trucks and a parts truck, all long beds. This Cheyenne is probably the nicest.
Ive got a 383 stroker in my shorty chevy van. 700r4 trans its getting 373 gears soon. I feel my stock/original converter is too tight at 1500rpm. Like the motor is fighting it at idle speed. Id like a 2000ish converter. Im not racing. Does that sound about right? What is the stall speed on this converter in the video?
Behind this 383 it stalls about 24-2500rpm. The converter was built originally built for a turbocharged 5.3 ls. Behind 700ish hp, it should stall about 3700rpm. The cam company recommends a 3500 with this camshaft. This converter is just a little tight for this engine. I had a 2400 b&m behind the old goodwrench engine & loved it. What's your cam specs? That will more closely determine stall speed.
I used a 2800 stall converter behind my 383.
Just get a stock convertor for a 4.3 engine. They stall higher than the V-8 engines. My son has one behind his 383 and it works perfect.
@kennydemartini2169 I drove a heat & air van for a guy yrs ago that had a 4.3. It did seem to stall weirdly high. It didn't seem like a good match to a 4.3 at all. That thing was gutless as they come. Would be way better with a v8 in front of it.
Question is that cam small base circle.900
Good question. Howards doesn't say anything about it being a small base circle cam on the site or the cam card 🤷♂️
Pretty tame cam by the sounds of it......a rough cam will make your engine sound like it has blower surge
My thoughts also.My factory RA/IV cam had more pop than this at its 1050rpm spec.Tried to lower the idle down once,and when it hit 650rpm it backfired and died.It was not meant to be coupled with a stock M40 auto,so I had to set the idle up to 2000rpm to drive it home from my dad’s garage.In gear it would drop to 750rpm,but would lurch (pulsate)with the front end moving up and down.It was lurching like this when a cop pulled up next to me at a light.He lit me up,then told me it was not streetable,if he sees it again he will write me up.Had to put a stall in it for drivability.This 70 crate engine was dropped into my 1964 GTO.
@babaoreally8220 this cam is around 250° and .600 lift. It's tuned up with 20° of timing at idle and a short curve. I gave it that much timing to help out the idle quality. When I first got it running the dizzy had something like a 26° curve. With 10° initial this engine would idle like a dying pig.
@@jdbas71 agreed,10* for a hot cam is way low.The way they are measuring these durations up the ramp now is difficult for me to convert to the classical spec.I love to hear those thumpers in a pick-up truck.There’s one (mid 70’s) next door that really pops,and I wander over to take it all in.Sounds like someone banging a bass drum when sitting in the living room.The factory cam in mine was a heavily double sprung hydraulic,but you could hear the valves snap shut,like a solid lifter.The construction of the lifter was such that it acted like a solid lifter as rpm’s got higher.The 308/320* duration and .530 net lift was the most radical of GM’s factory engines.
That is a pretty big hydraulic he is running did you even look it up or just listen

What is your tire dia and axle ratio?
I see the fuel gauge works. Not sure if it matters.
I got everything but the speedo working. Really just need to invest in the converter box to run it.
@@jdbas71 the flex lines need slicker grease but the dang square extension wears down. The truck looks awesome in the original paint though. Hard to justify fixing it up in new. Still looks great!
@benhudman7911 and to think..... 11ish yrs ago, when I found it parked non running, my initial intention was to part it out to fix my grandpa's gmc. I got the original engine running and washed and waxed it. Went all downhill from there. There's no way I could part it out then. It just became part of the collection lol.
You gotta look real quick?
I like it!
Thanks
Needs good heads, hence the small split in duration at .050
Where you from? That’s some awesome land.
Central Kansas. Everyone says Kansas is flat but just gotta get off I70.
@@jdbas71 looks great to me. I’m on the east coast. I always wanted to go to Arkansas
@@jdbas71My last duty station was Ft Riley. Kansas is definitely not flat...
@@redherring4335Thank you for your service!!! 🇺🇲🦅🇺🇲
I worked at Wolf Creek Nuclear Creek power plant for about 9 months in the mid 80s I liked it out there but had to get back to Carolina. Great sounding truck. You should be proud of yourself. You did a great job.@@jdbas71
The truck is cherry man.
@@rick-wg4in Thank You!!
Want to know if u think it's big cam who would have read line at 5 grand. Have a Monte big block 680 lift drive every were 7800 all the time Cruz Town all day
😆 I had a grip of people tell me i over cammed my small block for the street. 😆 I laughed because they probably tried it and dropped thier stock hei in, set the timing to factory spec and it ran like shit. If the tune is right, ya can get some really radical engines to have really great street manners.
In all actuality, the redine is just there. I slide that thing around all the time because I don't have a working speedometer at the moment. Set it at my intended hwy speed and keep it somewhere close to that. It has a rev limiter so I ain't to worried about a "redline". A guy can rev an engine to 8k all day but really pointless if it peaks hp around 6k.
Thank you for saying that my thoughts exactly
C'mon Grandma I'll drive you to the Hospital.
"But I'm not Sick"
You will be in a minute. Hang On.
😆🤣😆Thanks!!! I needed that laugh!!! That's the best one yet!
You really need a vacum gauge on it for what your doing! It helps alot!
