I'm so glad you came to UA-cam. After reading many of your articles in magazines, I learned about your books and now I'm getting a direct lesson on power production from the man himself. Killer content uploaded regularly.
For as much as my dad knew about engines he never went out to race after we kids were born. When he had met my mom he was in the air force and had a cool ass hot rod I can’t remember what it was but it was hard to handle after throwing up the switch to get more fuel. He knew a great deal. Fords were his favorites.
It's interesting that the 351w flat tappet had that hot of cam. When the fuel injected 5.8 came out in 87 or so we (at a Ford dealer) had trouble with them idling smooth. The fix was a different PCM with updated fuel curve at idle. The service engineer told us they had a "hot" cam and that caused a lot of the rough idle. Maybe he was right.
Thanks so much for this info Richard. Love watching this stuff as a small block ford guy. Currently running a 95 GT short block, GT40 heads, dual plane intake, E303, 1 5/8” headers, and topped it off with that same perimeter plate for an extra 150 hp, in my sub 3000 lb 65 mustang. Car is a blast to drive!
Had a 77 mustang stock 302 2v. Smogged to death.. 120hp from the factory. "Back in the day" added flat top pistons [9.5:1], ported with carbide bit in a drill, 1850 holley on an edelbrock manifold with blackjack headers. Was around 300hp. Hot snot back then. Hard to believe nowadays!
The dyno graphs really tell the whole story. Often times chasing that high power number is a trade off in reduced lower rpm power. If you're just building a cruiser the mild engine with more power off-idle to 3500 rpm may be a better choice than one that has a magic number at 6-7000 rpm. Especially in a heavier car or truck with an automatic.
There is a good combo for midrange < 5500 but the numbers are not as impressive. Fun to drive IS. Fox 90 here. Never forget that big power starts slipping clutches, popping transmissions, overcoming suspensions ... SNOWBALL $$$

I remember running this guy back in the day, he had a bone stock '86 and he put a 100+ shot of nitrous on it. He was real fond of toying with other drivers by hitting the spray and leap frogging. Everyone knew those '86 motors were turds, which made it all the more frustrating that he just bolted on liquid horsepower. I never ran him for money, and it was back when I had a more-or-less stock engine. There was this big winged Saleen replica that would show up with a built motor and supercharger, they only ran for money. I saw one guy show up for a dyno day at Apex Motorsports, he literally had just bought a 351W engine the day before and never ran it, he flogged the crap out of that motor while Byron tuned it. Once done he went off and conducted a little business, then came back. Dude had no respect for his car, it was a stock shell that was stripped, no safety, just slicks. Those cars tended to potato chip and rip apart...no respect.

Use a comp cam 35-218-3.You can still use your factory torch converter if you can find some gt40 heads cheap use them but upgrade the springs to match the cam.Change out the intake to a dual plane Weiland.Put in limited slip if you don't have it know.Use a 3.73 gear and now you have plenty of towing capabilities.I have this set up but use a 3.90 gear and the torch is amazing.
I made 327 back in the mid 2000s with a 5.0L short block. Extensively ported 289 heads, Crane 272. Edelbrock RPM and a Holley 4150 with a 2” tapered spacer.
At a car show i sprayed my stock rebuilt 85 longblock with 100 timing was at but 8*. The temperature outside was 90*. It made 290hp and 426tq. The car had 4.10 gears and basic intake carb and exhaust and a manual transmission. With a crap tire it ran 7.70@90 in the 1/8 and 12.56@100 in the 1/4 ran out of gear at 900'.
I liked this video alot. I recently purchased a 86 f150 2wd with 5.0 fi moter. Its in excellent condition & all stock & though its power level is what I consider adequate, I want to make fun. I dont have a ton of money to dump into it & dont need to race it, just make it a quick ride (for a 86 150). So a basic cam upgrade & shorty headers & depending on what heads it has, possibly a gt40p head upgrade.
@@sknallt2010 I’m running a set on my carbed 95 gt they are great, I even found a pair of brand new 90$ headers that fit the weird gt40p bolt pattern and spark plug angles
How about a 2.3 Lima Pinto/Mustang/Thunderbird/Ranger build? Buddy Ingersol was running 10.30's with his 2.3 Pinto with 26 lbs of boost and 6.50 gears back in the 70's. Maybe build a later 2.3/2.5 dual plug roller Ranger motor - they're probably plentiful and cheap in the junkyard.
I enjoyed the video. However, not everyone wants a cam swap for a 300hp motor nor is one required at that power level. Most cars with actual 300hp engines are in street cars and daily drivers. Choppy cam is cool but at 300hp, so is the element of surprise that comes with a smooth idle paired with GREAT DRIVABILITY. The stock HO cam is a diecent piece. Pair that with rebuild GT40 HEADS, mill them to 58cc add 1.7 rockers a diecent intake and you'll have a smooth running and very responsive package making just above 300hp. Also if your an EFI guy the stock upper and ported lower will support that engine with the stock injectors and adjustable fuel pressure regulator. Just upgrade the mass air housing and add a 65mm throttle body. Now that's cool and stealthy as well. Add nitrous and you will have a can of woop ass no one will see coming. Many big block chevy vehicle's back in the day have lost money and street races to what people called stealth stocker builds similar to this combo. Me personally I use World Products Windsor Sr. milled down to 58cc. They work GREAT and you'll have more than enough room to grow down the road.
@@SophiaAphrodite yeah I agree with the heads, but not everyone wants a cam change or needs one to get 300hp, when you have a stock H.O. cam. Especially when drivability is a concern, and it's gonna be a daily. In that arena it's best to save the money.
Explorer motor with short tubes and e cam in a 95gt did 265hp/300tq at the tires. 351w stock compression, performer rpm heads/intake, x cam. Did 325hp/380tq at the tires too. Same car
One thing I don't understand when tuning the small, small blocks is why their high rev capability is not used to make power up to at least 7000 rpm. Making max power to 5000 is pointless with, say a 305 when a 351 will do the same with an obvious advantage in torque. So I would be grateful if info on the high revvers was linked.
...Can't wait to see your 400 hp Combinations! Thanks for the videos! I wish I could see the Dyno Runs. At what HP do you suggest changing the Connecting rods to aftermarket forged?
Stock explorer short block Ported 170 twistwd wedge heads milled to 58 cc, .035 headgasket N412 cam Ported upper and lower intake Ported throttle body 24 lb injecters at 65 psi fuel pressure Hope to be 400 to the flywheel. Well see very soon!!
@@johndoe-zb8bm Yes sir we do!! Love them! Everything I have on the top end is ported by him.. dude is a pro at what he does!! Now..Im just waiting on injectors.. couple small things.. get thing fired up and see what it does..
Im building a long block 5.0 from a 96 explorer with f303 cam and springs im planing use a gtp38 turbo from a 2000 powerstroke engine im trying some 400 hp at Wheels with a c4 transmission
In all those videos he says with the right springs and whatnot in the cam you can make your explorer motor awesome but I can't see where he actually says what springs you need
GT40 is basicly the 69-73 big spark plug 351w head.... which back in the day was a good +20 hp but lowered compression on 289. 289 = 124 cc intake/54 cc chambers GT40 = 144 cc intake/60+ cc chambers
@@hotrodray6802 to follow up the GT40p heads have smaller exhaust valves so if you intend to put in ANY cam over .500 you will want to port it or that lift will be wasted and should stay below .520. But porting them will get you +50 bolt on HP without any other changes.
Check his channel he has a couple videos, just v8 swap your s10 instead my guy building those 4.3Ls are money pits that don’t really bring that much performance even compared to a stock 4.8L LS and the crankshafts are stupid easy to break my crankshaft completely destroyed itself even when I was just daily driving my s10 and maintained it well
I bought a new 5.0 LX notchback in ‘89 and enjoyed it even if it was a Ford. My daughters, in high school at the time, had a ‘66 289 4bbl 4-speed coupe. The ‘89 did everything better than the original, even if both were fun. These days I’d ask why not find a 4.8 and do a swap? No mods necessary, until you get tired of 300+ and need 400+, or 500+ (turbo).
I am Rebuilding my 302 and this is what I have so far. Forged pistons from a 302 HO engine, the block, crank, and head got cleaned up at the machine shop everything was good, and I also have a B Cam. My question is what type of roller rockers should I go with what size fuel rail and injecter?
Great videos, but wondering if you could test some small changes such as titanium retainers, titanium valves, metric LS style (thinner) rings, windage tray, milling for a bit more compression. Would be good to see what works on more specific things. Thanks
@@richardholdener1727 Just interested in what can be squeezed out of a 302. You know your stuff, so if you think its not worth it, I will take your word for it.
Video idea. How about who makes the most efficient mechanical water pump test? Just curious and came from the thought that if you dyno a motor at 300HP on the dyno then put it in a car then its no 300HP anymore, but somewhere around 320HP dyno would be 300HP in engine bay with pump and alternator.
So an aftermarket head lists a maximum lift. (i.e. TF GenX 220 "as cast" = .600"). What is the limiting factor? The provided spring or an actual mechanical limitation of the head itself? I was going over the specs more closely and some of the camshafts I have seen used exceed this. Thanks in advance.
@@richardholdener1727 I tried to contact Trick Flow. No luck. Called Summit Racing and they were a big help. There is a valve train upgrade kit (CCA 26926TS KIT) with upgraded PAC dual springs, steel retainers, and keepers. $487usd adder that is good for a .624 lift cam. $605usd for titanium retainer upgrade.
Great video, any idea how much power and torque the afr 165 heads are worth with a mild cam , dual plane edelbrock performer rpm intake , 650 carb and long tube headers ? Thx !
Timely info. I havent much expeireance with sbf but just started a project with my wife swaping a 91 5.0 out of a lincon into her b2200. Were putting a e303 and 4 barrel intake on it with headers. I dont know if the heads would be the same as a mustang of same year? How much power could we expect from it? Thanx for your vids
I had that combo in an early Capri. Ran a torker 2 intake, stock carb (heavily modifed for good fuel economy and power), headers, can't remember the cam but it wasn't too radical. Shifting out of first it liked to go to 6500 rpm before I had time to shift. I had Comp Cams roller tipped rockers and they liked to "roll over" and cause misfire unexpectedly and found out the camshaft bearings were flaking and apparently a flake would get caught under tappet and cause momentary clearance the rockers couldn't take. I had 100k miles on the bearings. Ran the combo for 50 k miles. Could still get 18 mpg on trips and pull my pop up camper too (reduced fuel mileage).
Best running naturally aspirated 302 I've had in a long time was a 302 w/ '69 351W heads only lightly cleaned up. Medium flat hydraulic, Holley Street Dominator intake, mid-length headers, 700DP. What a responsive little mill it was, and strong for any iron-headed inline valve 302. Would like to have run it in comparison to the Edelbrock aluminum equipped two that I have had. One was superchared and the current one is MassFlow injected. That little all iron one would kick this one's behind, but the blown one had a lot more going on. Still, I believe the iron one would have acquitted itself well. Of course, Ed doesn't do Ford heads very well, so I'm sure a set of TFS, Kaase or AFR heads would have put that iron mini-engine in it's place. For what they are, though, I think you'd like the results if you use pre-'77 heads.
So, I'm curious. That 274 degree cam...is it factory computer compatible? Or is a custom tune required? I'm shopping for a camshaft now for my build. Hyd roller 1994 5.0l gt40P heads tfs spring kit. Explorer intake and 75 mm throttle body 24# injectors. 🤔
I got 340hp out of my 2v Cleveland with a r.v. cam a little porting of stock intake/heads and a 500 holley 2bbl. Its not hard....(rated at 180 stock i think...)
351w flat tops, p heads, 230 @.50. .500. Lift. Did 290 at the wheels. Using the scary lean stock tune from my sn 95 computer. Don't remember the tq, I'm sure it was above 350 at the wheels
Richard, quick estimate please? Junkyard 351/gt40p heads/ .512 lift and 230&.050 cam? 300hp? 325? Instead of putting this on a 302, might as well go 351. Oh, and headers will be 1 3/4 long tube homemade by me. 40" primaries and 3" collector...or...what do you suggest for that too I guess, don't have pipe max.
Really? Thanks for that. Bracket racing and can't go over 300 or I'll be in the next higher class so if it works that well I'll put a bolt under the throttle.(83 mustang, c4, 3000 stall, 9" with 4.86's and 29.5 X 9 slicks). Approximately 3000lbs. I think I'll be swapping to 3.50 gear though, what would you say is max rpm for stock rods/bolts/cast Pistons? I'm thinking 6000 which the 4.86's will hit by half track. Thanks so much for sharing your knowledge in the videos and comments section!
Ok, you got me thinking so I went to Wallace auto calculator and 3000# and 325hp is 12.2@110mph. With 4.86 and 29.5 puts it at 6400 in the traps. Going to a 3.50 gear brings it down to 4600.... I think I'll be switching rear gear when I drop in the 351. I might even go to a 28 X 10 slick as my current ones are pretty old. That'll put me right at 5000 in the traps. Thanks again!
@@richardholdener1727 Holley High ram as far as Cam unsure yet I'm doing a junk yard 351W slap the high ram and terminator X in my 1990 2wd toyota pickup that already has a Ford 8.8 3:73 posi in it and a T5 or T56 what ever I score at the junk yards and have a fun truck
With a 1969 GT350 351W had an, ahem, aftermarket Shelby C90Z-C cam (OZ= ozzy ozzy ozzy) 290/290 duration with 470 lift 62 degree overlap and a Buddy Bar dual plane, 300 hp net at 5400 rpm option.Same head flow as the GT40Ps. Use cast iron Drake Remade K code C3 headers to pass the plug angles, but C9 4v Windsor heads were inferior to GT40Ps. Factory Ford Falcon Phase I GTHO spec with 600 cfm Holley was the non emisions version California and AO Smith werent allowed to build.
I've got a stock 2000 Explorer 5.0 and it's pathetic above 3500 rpm. I wonder what it's power level is with stock cam. I wonder if one stuck in just a little more powerful HO roller cam?
If it has the GT40p heads thier exhaust valves are smaller than a typical GT40 as well so need port work if you intend to run anything over .500 lift. Keep it below .520 if you are running GT40's without any porting.
IF you do not port those GT40p heads with that lift you will actually lose potential HP because the exhaust valves are smaller and you start to drop flow past .500 in stock. Porting you still should stay below .520. You might get away with that lift in ported GT40 heads though.
Hopefully this is seen or commented on, My build is a 306, N-41 Cam, Afr 185 heads, Edlebrock performer RpM ii, 24# injectors and maf, as well Bbk longtubes. 1.6 roller rockers as well. Do you guys think it will make 300WHP+?
Looking to upgrade my Speed density to MAF 87 Fox. Currently still has the e7's. Have 1.7 Crane Cobra RR's on the Stock Cam and a 93 Cobra Intake (replaced the Comp polymer bread box intake). Has 3:73's and MAC shorties with an O/R H-pipe. Question....best direction to get over 300 from here? Obviously I know NOS is a possibility. Your thoughts?
Alright I have a stock 86 302, I had the e7 heads ported at a shop for trade, I’ve got long tube headers, a dual plane intake, Holley 600cfm carb, and the comp cam 268h k31-218-2 & the kit with new springs and timing set. So What type of power would I be looking at? I hoping somewhere north of 270hp but I’m not sure! Any help would be appreciated, thank you
I have nearly the same set up. 86 stock bottom end. Ported GT40p heads. .512 cam, dual plane with a Holley 600 and I am predicting right near 300hp. Running automatic with a 1000 stall as well. It is going in a Ranger so I also have a weight advantage over a Mustang and most cars. That should make it very fun to drive and also not lose any driveability.
That being said without porting .512 is about the limit for flow for the GT40p as well due to the smaller exhaust valves. Even at .512 port those babies!
What kind of cam would you recommend in a ford 400 with 2v heads and around 10.3 compression? I've been told 240+ degrees at .050. I'm am getting some flat tops and putting them at close to zero deck.
@@socalltd thanks for the reply. I too have read that article. I have used a similar cam in a otherwise stock engines, it retained the low end power and worked well. I think that with 10.3 or 10.5 to 1 compression though I will need more duration.
Alex's springs are a good spring,I run trick flow springs in my GT-40 "3 bar" heads. But I'm not running a huge cam with a lot of lift. Big improvement over stock ,lol. I'm running about .525 lift.
Afr 165 on stock bottom end, stock cam, exporer intake with 1.7:1 roller rockers = 319 hp. Perfect reliability, drivability, and stock fuel milage with 50 lbs less weight over the nose

It's interesting that the 351w flat tappet had that hot of cam. When the fuel injected 5.8 came out in 87 or so we (at a Ford dealer) had trouble with them idling smooth. The fix was a different PCM with updated fuel curve at idle. The service engineer told us they had a "hot" cam and that caused a lot of the rough idle. Maybe he was right.
Yup and the aromatics shifted before 4500rpm so the roller made far more usable power on a "stock truck setup"
Came across the same specs and was certain the 351w flat tappet info was wrong. Never would’ve guessed those numbers.
I would love to see a power build up of the old Ford 300CID inline-6. That engine was indestructible.

I second this vehemently! Preferably with the 2 different heads and with the diff carb intakes and some fuelie stuff.

The car had 4.10 gears and basic intake carb and exhaust and a manual transmission. With a crap tire it ran 7.70@90 in the 1/8 and 12.56@100 in the 1/4 ran out of gear at 900'.
Thanks for producing these videos 📹 love the content.
Way excited for this series 👍
I liked this video alot. I recently purchased a 86 f150 2wd with 5.0 fi moter. Its in excellent condition & all stock & though its power level is what I consider adequate, I want to make fun. I dont have a ton of money to dump into it & dont need to race it, just make it a quick ride (for a 86 150). So a basic cam upgrade & shorty headers & depending on what heads it has, possibly a gt40p head upgrade.
Heads and a short duration high lift cam. Headers are always a great idea.
The second to last test with GT40P heads! So, 70mm TB, Explorer heads & intake with the 274 cam, B303 or E303 cam. Please.
Get something better than a letter cam they are outdated compared to some of the stuff you can get now
+1 for GT40P heads
Yes!!! Need the vid to go the full monte with the Cobra GT40 intake!! Add the Ex heads and a nice street cam. Preferably not an alphabet cam tho.
@@sknallt2010 I’m running a set on my carbed 95 gt they are great, I even found a pair of brand new 90$ headers that fit the weird gt40p bolt pattern and spark plug angles
BigDogs Porting fi intakes are superior and half the $$.
How about a 2.3 Lima Pinto/Mustang/Thunderbird/Ranger build? Buddy Ingersol was running 10.30's with his 2.3 Pinto with 26 lbs of boost and 6.50 gears back in the 70's. Maybe build a later 2.3/2.5 dual plug roller Ranger motor - they're probably plentiful and cheap in the junkyard.
I enjoyed the video. However, not everyone wants a cam swap for a 300hp motor nor is one required at that power level. Most cars with actual 300hp engines are in street cars and daily drivers. Choppy cam is cool but at 300hp, so is the element of surprise that comes with a smooth idle paired with GREAT DRIVABILITY. The stock HO cam is a diecent piece. Pair that with rebuild GT40 HEADS, mill them to 58cc add 1.7 rockers a diecent intake and you'll have a smooth running and very responsive package making just above 300hp. Also if your an EFI guy the stock upper and ported lower will support that engine with the stock injectors and adjustable fuel pressure regulator. Just upgrade the mass air housing and add a 65mm throttle body. Now that's cool and stealthy as well. Add nitrous and you will have a can of woop ass no one will see coming. Many big block chevy vehicle's back in the day have lost money and street races to what people called stealth stocker builds similar to this combo. Me personally I use World Products Windsor Sr. milled down to 58cc. They work GREAT and you'll have more than enough room to grow down the road.
Yeah a ported set of GT40 or GT40p heads with a mild cam can get you to 300hp.
@@SophiaAphrodite yeah I agree with the heads, but not everyone wants a cam change or needs one to get 300hp, when you have a stock H.O. cam. Especially when drivability is a concern, and it's gonna be a daily. In that arena it's best to save the money.
What's even more amazing is that the stock head is a 125cc runner, yet it'll make 1HP/CID
Yeah, but that's about it.
Stock heads only flow about 150 CFM. Which is excellent for stooging around town, but.....
GT 40 are 144cc and flow about 170.
Explorer motor with short tubes and e cam in a 95gt did 265hp/300tq at the tires. 351w stock compression, performer rpm heads/intake, x cam. Did 325hp/380tq at the tires too. Same car
Lift weezed out 5 liter out, drop fresh 5.8 liter with heads, cam, intake!! Replace rear tires frequently! Been there, did that!😂😂
I would like to see what the budget 302 rebuild do with a set of explorer heads and mild a 248 or 352 cam
Good stuff Richard!
One thing I don't understand when tuning the small, small blocks is why their high rev capability is not used to make power up to at least 7000 rpm. Making max power to 5000 is pointless with, say a 305 when a 351 will do the same with an obvious advantage in torque. So I would be grateful if info on the high revvers was linked.

Hey Richard could we get some flat tappet 302 content? Either video or a write up?
Sbf power 4 ever!
Are you running that xe274hr with factory pistons on the 302?
Great video !
which valve springs is recommended for this application
In all those videos he says with the right springs and whatnot in the cam you can make your explorer motor awesome but I can't see where he actually says what springs you need
Fuck yea man!! Been waiting on some 289 numbers!!!
you can make 300hp flat on a SD truck block using long tube headers and a E cam. i’ve done it and dyno’d it
I’d like to see what power gains the 351W would get from Holley Sniper, FAST, or one of the other injection carburetors.
Well, if you still have it what are you waiting for, put a 351 in it
Not ls! 👍
I wanna see what you can squeeze out of a mid 90s 302 truck motor running the factory manifold and dual tb
heads and cam still help-just gets held back but the stock intake
I would love to hear your thoughts on the promaxx heads for the price they look like a good choice?
I have a 95 mustang. .030 over forged pistons , rods, 165 AFR heads , E303 cam , roller rockers , 24# injectors , ‘95 cobra intake , larger TB , cold air kit , billet distributor , cat-delete, shorty headers , flow masters ,custom chip. I assume a fair guess would be 340 lbs/340 HP
pretty accurate-might be a touch more-those R good heads
Richard- can you tell the differences between a 289 Hi-Po head vs. the newer GT40 or GT40P head?
GT40 is basicly the 69-73 big spark plug 351w head.... which back in the day was a good +20 hp but lowered compression on 289.
289 = 124 cc intake/54 cc chambers
GT40 = 144 cc intake/60+ cc chambers
@@hotrodray6802 to follow up the GT40p heads have smaller exhaust valves so if you intend to put in ANY cam over .500 you will want to port it or that lift will be wasted and should stay below .520. But porting them will get you +50 bolt on HP without any other changes.
coyote big bang comment influenced by rum: some assembly required batteries not included. Also drop forged
Have you ever done a chevy 4.3 for us S10 guys?
Check his channel he has a couple videos, just v8 swap your s10 instead my guy building those 4.3Ls are money pits that don’t really bring that much performance even compared to a stock 4.8L LS and the crankshafts are stupid easy to break my crankshaft completely destroyed itself even when I was just daily driving my s10 and maintained it well
Love the videos. Holley sniper efi
I bought a new 5.0 LX notchback in ‘89 and enjoyed it even if it was a Ford. My daughters, in high school at the time, had a ‘66 289 4bbl 4-speed coupe. The ‘89 did everything better than the original, even if both were fun. These days I’d ask why not find a 4.8 and do a swap? No mods necessary, until you get tired of 300+ and need 400+, or 500+ (turbo).
Right on
These videos are great

I am Rebuilding my 302 and this is what I have so far.
Forged pistons from a 302 HO engine, the block, crank, and head got cleaned up at the machine shop everything was good, and I also have a B Cam. My question is what type of roller rockers should I go with what size fuel rail and injecter?
STOCK RAIL AND 36 POUND INJ WILL BE PLENTY
Awesome!
Great videos, but wondering if you could test some small changes such as titanium retainers, titanium valves, metric LS style (thinner) rings, windage tray, milling for a bit more compression. Would be good to see what works on more specific things. Thanks
high $ titanium parts in a 300-hp combo?
@@richardholdener1727 Just interested in what can be squeezed out of a 302. You know your stuff, so if you think its not worth it, I will take your word for it.
Is there a way to make NOS come on in a more linear fashion like a supercharger and not so sudden?
Most definitely, use of a nitrous controller. You can adjust how much and at what times and set different stages
and the ZEX system that reads bottle pressure prevents bad things...
Richard, how about the other guys Toyota and Nissan V8s?? Junk yard has a few of those, no?
I'm in for those. The VQ56 in my NV2500 work van gets the 6000+ lb. whale moving along nicely.... it has some grunt.

you cannot
Richard doesn't seem to rest much....
Why rest? You only live once.
Video idea. How about who makes the most efficient mechanical water pump test? Just curious and came from the thought that if you dyno a motor at 300HP on the dyno then put it in a car then its no 300HP anymore, but somewhere around 320HP dyno would be 300HP in engine bay with pump and alternator.
watch the accessory video on the LS
@@richardholdener1727 so the LS water pump is the most efficient?
So I have seen this claim that you can make 400hp with a stock 5.0 ho short block and stock ho roller cam n/a. I'd love to see that
I SAW THAT SOMEWHERE-I DOUBT IT
Matt King did it on his road course car.
That is a lot of carb. Do you like the holleyHP? Did you tune it for the different combos?
yes we tune every carb combo
LS guys are laughing at how much us Ford guys have to spend just to get into the playing field...😒😂
Facts!!!!
Good cylinder heads and a cam.and you're there.
So an aftermarket head lists a maximum lift. (i.e. TF GenX 220 "as cast" = .600"). What is the limiting factor? The provided spring or an actual mechanical limitation of the head itself? I was going over the specs more closely and some of the camshafts I have seen used exceed this. Thanks in advance.
SPRING COIL BIND, OR RETAINER TO SEAL POSSIBLY
@@richardholdener1727 Thanks for the response. I think it merits investigation. You have recommended these heads and cam combinations.
@@richardholdener1727 I tried to contact Trick Flow. No luck. Called Summit Racing and they were a big help. There is a valve train upgrade kit (CCA 26926TS KIT) with upgraded PAC dual springs, steel retainers, and keepers. $487usd adder that is good for a .624 lift cam. $605usd for titanium retainer upgrade.
Great video, any idea how much power and torque the afr 165 heads are worth with a mild cam , dual plane edelbrock performer rpm intake , 650 carb and long tube headers ? Thx !
Im building a hydraulic roller 351w, and am looking to do a cam and aluminum heads, how important would an intake manifold be to make power?
Very, it affects your power curve drastically! Long runners are better everywhere except the very top of the rpm range

@@KreatorOfDeath1985 I mean more specifically in terms of budget.
Timely info. I havent much expeireance with sbf but just started a project with my wife swaping a 91 5.0 out of a lincon into her b2200. Were putting a e303 and 4 barrel intake on it with headers. I dont know if the heads would be the same as a mustang of same year? How much power could we expect from it? Thanx for your vids
I guess 258 hp haha
I wonder what early 351 heads that are ported and larger valves would do on a 302? I have one with domed pistons 11-1 comp haha
I had that combo in an early Capri. Ran a torker 2 intake, stock carb (heavily modifed for good fuel economy and power), headers, can't remember the cam but it wasn't too radical. Shifting out of first it liked to go to 6500 rpm before I had time to shift. I had Comp Cams roller tipped rockers and they liked to "roll over" and cause misfire unexpectedly and found out the camshaft bearings were flaking and apparently a flake would get caught under tappet and cause momentary clearance the rockers couldn't take. I had 100k miles on the bearings. Ran the combo for 50 k miles. Could still get 18 mpg on trips and pull my pop up camper too (reduced fuel mileage).
Best running naturally aspirated 302 I've had in a long time was a 302 w/ '69 351W heads only lightly cleaned up. Medium flat hydraulic, Holley Street Dominator intake, mid-length headers, 700DP. What a responsive little mill it was, and strong for any iron-headed inline valve 302. Would like to have run it in comparison to the Edelbrock aluminum equipped two that I have had. One was superchared and the current one is MassFlow injected. That little all iron one would kick this one's behind, but the blown one had a lot more going on. Still, I believe the iron one would have acquitted itself well. Of course, Ed doesn't do Ford heads very well, so I'm sure a set of TFS, Kaase or AFR heads would have put that iron mini-engine in it's place. For what they are, though, I think you'd like the results if you use pre-'77 heads.
So, I'm curious. That 274 degree cam...is it factory computer compatible? Or is a custom tune required? I'm shopping for a camshaft now for my build. Hyd roller 1994 5.0l gt40P heads tfs spring kit. Explorer intake and 75 mm throttle body 24# injectors. 🤔
tuning should be required, but i ran it with a Pro M MAF and no tuning back in the day
not a huge car guy but i have a 92 foxbody and im looking to get a crate engine with around 300hp anyone have suggestions?
EXPLORER 302 FROM JUNKYARD, SPRINGS AND XE274 CAM

Dude, "RV" cam ? There is no such thing it's just what we used to call a "torque" cam.
what type of pistons do you need for the twisted wedge heads? Would hypereutectic cast valve relief pistons work?
you need TW specific valve reliefs (some pistons have both)
I ran stock pistons with TW heads with both stock & B303 cam back in the day.
Don't you have a video of a 302 with the Ford Lighting intake vs a Ford explorer intake?
351w flat tops, p heads, 230 @.50. .500. Lift. Did 290 at the wheels. Using the scary lean stock tune from my sn 95 computer. Don't remember the tq, I'm sure it was above 350 at the wheels
up the fuel pressure to 43 with the stock injectors.
Richard, quick estimate please? Junkyard 351/gt40p heads/ .512 lift and 230&.050 cam? 300hp? 325? Instead of putting this on a 302, might as well go 351. Oh, and headers will be 1 3/4 long tube homemade by me. 40" primaries and 3" collector...or...what do you suggest for that too I guess, don't have pipe max.
more than 325 flywheel
Really? Thanks for that. Bracket racing and can't go over 300 or I'll be in the next higher class so if it works that well I'll put a bolt under the throttle.(83 mustang, c4, 3000 stall, 9" with 4.86's and 29.5 X 9 slicks). Approximately 3000lbs. I think I'll be swapping to 3.50 gear though, what would you say is max rpm for stock rods/bolts/cast Pistons? I'm thinking 6000 which the 4.86's will hit by half track. Thanks so much for sharing your knowledge in the videos and comments section!
Ok, you got me thinking so I went to Wallace auto calculator and 3000# and 325hp is 12.2@110mph. With 4.86 and 29.5 puts it at 6400 in the traps. Going to a 3.50 gear brings it down to 4600.... I think I'll be switching rear gear when I drop in the 351. I might even go to a 28 X 10 slick as my current ones are pretty old. That'll put me right at 5000 in the traps. Thanks again!

Great video Richard. Are the stock GT-40 heads better than ported, small chamber, 1.9/1.6 valve (if I remember correctly) 289 heads?
depends how bad the porting is
David Vizard heads are tops, but $$$$$$
I've got a stock 2000 Explorer 5.0 and it's pathetic above 3500 rpm. I wonder what it's power level is with stock cam. I wonder if one stuck in just a little more powerful HO roller cam?
The valve springs are weak and the exhaust manifold design is brutal!
There's nothing wrong with the cam really, it is the ho cam spec, it's okay.
If it has the GT40p heads thier exhaust valves are smaller than a typical GT40 as well so need port work if you intend to run anything over .500 lift. Keep it below .520 if you are running GT40's without any porting.
What's part # for valves springs using 264 cam? Or what springs I need for gt40p heads with .550 lift?
David Vizard says beehives.
IF you do not port those GT40p heads with that lift you will actually lose potential HP because the exhaust valves are smaller and you start to drop flow past .500 in stock. Porting you still should stay below .520. You might get away with that lift in ported GT40 heads though.
