Not dissapointed at all. Anything over 400 hp on a budget with used parts is something to be proud of. Keep it up !
I was happy with anything over 450hp/440tq
Nice little street engine. I think a lot more people are building budget engines these days and really appreciate the effort you put into making these videos. Good work as always 👏 👍.
Thank you appreciate that!
In a world full of 1000hp Ls, coyote, and power adders. It's nice to see some old school getting revisited. 👍
Got a 355 sbc in my 1991 s10. I can’t wait to dyno it
I ran this exact motor combination in my dirt car. I turned 7200 all night long. Never no issues
That power on the cheap is nothing to be sneezed at.
Yes, do a video breakdown of the parts on dingleball 355.
Love to see the parts list.
Yes I would like to see the part list..
I recall a DV article probably decades ago where he made 470 with a 355 and Vortec heads. If memory serves (I’m old), he used a 236° cam with 108 LSA, just a bit shorter than yours. Very impressive results regardless! Thanks!
Sickness...great job on the HP number. Love how this reminds everyone how good the SBC is.
That 300hp at 3500 rpm is very impressive.
Its approx 300hp by 3800 to 3900 rpm on most pulls
Can’t wait for the roller cam version. I’m currently building a vortec 350 with summit racing 8803 cam and aluminum heads.
Thats really impressive considering what it is. I know some 383's that struggle to achieve at least hp numbers this has made. With vortec heads..awesome. Love your channel!
I'm impressed that 11 to 1 CR played nice with less than 100 octane. I've always heard no more than 10-10.5 to 1 on CR with iron heads - for pump gas/street-driven engines.
Ive done 11:1 before with vortecs but was worried with the dyno load it might detonate. We tuned it up with VP additive mix, but it actually made the best power on 94 octane at 35 deg. I wish I had brought more of the VP mix as it would have probably have taken more timing. Maybe get abit more out of it with few more degrees and a tapered combo spacer on higher octane
Excellent work Pat.
This is why it wouldn't work on a heavier vehicle? Detonation?
Thank you for sharing all your hard work
Awesome 👌 Great work Pat!
Super impressive numbers using mostly stock components (cam and intake not included of course). You must have got the porting just right for the combo. Adding compression sure builds power. Nicely done sir!!
Thank you!
Always look forward to your videos
67 pulls? Damn, about ready for a rebuild!! After 150 passes, I rebuild mine! :)
Thanks Patrick, love the video and the detailed info, great stuff!! We're going to be switching over to a SBC format from the BBC we run now next season for our bracket vehicle, so all of this info is really a big help! 💪
I was worried cutting the oil filter apart after 67 pulls, but she looked clean 👌
Thank you!!!
Thank you so much for including the idle vacuum numbers! I like my power brakes.
Great content on the venerable small block Chevy. Thank you!
Super grateful I found your channel. Im using it as a guide for my low budget Vortec build. Love the content!
Yeah, I'd like to see the parts list, too. Great channel by the way, thanks for all you do.
That spray distribution looks great!
Thats awesome!
Looking good!
Nice job! That new summit cam is money!! Their new grinds are actually legit...Thanks for sharing..
One word Amazing
The Dingle ball 2.0 video is coming soon!
Good numbers for sure!!
Keep it up! Best automotive channel out there
Definitely not, but I appreciate it haha
Those are crazy good numbers for that combo.
I would have been quite happy if he got in the 460s. 480s was a nice suprise
That's a very nice 350!
Thanks. Gonna try this in my short bed 89 chevy
Nice job! Very similar to my 327-street engine. I use a cam with better idle vacuum and take the hit on HP, but otherwise very similar. Using Dart 2 heads instead of the Vortec units also. I am looking forward to the carb vs injection results. If not port injection, I prefer the double-pumper Holley 4150 every time.
Very similar but shorter stroke, different cam, and different heads, sounds almost identical to me!!!
Hence the word similar, not identical. : )@@jcanfixall1585
Impressive!
Wow awesome 👌
You power brake guys, get a vacuum canister and your brakes will work excellent
Only making 7 inches at idle and my brake feels factory perfect with a canister. No need to go manual brakes, pumps etc. Keep er simple
Curious to throw a set of Rhoads lifters in compare....vacuum especially. Guys will trip on the difference in idle note esp when the oil gets warm.
Im going to be trying that with Rhodes lifters
So glad to see some more content. Love the sbc stuff. U should build a gen2. They're damn near the same
Great torque curve, especially for a single plane intake.
That 108° cam really works
Good build brother
Thank you!
Nice work! That vortec headed 355 makes some power. Looking foward to more details on the dyno pulls.
It looked and sounded really cool on the dyno, nice to meet you!
Thanks man, maybe see you again at Luke's
@@cuttersperformance Probably! 😅
Thatll b a hard charging lil engine, nice job
Very nice,like to see the parts list also thanks,nice build!!
Pat The new shop look is 🤩💪🏻👍🏻🏁.
Thanks man!
Amazing knocking on 500HP. :)
Man I love your videos
Appreciate that!
Stout for a basic sbc, nice job putting the combination together.
Really like the video I would love to build the same exact engine. And put it in my S-10 keep up the good work.
Awesome job
Thanks brother!
I put a set of vortec heads and an edelbrock dual plane. With srp flat tops. And an isky r.v. cam. Back in the late 90s . In my 78 pick up and it made a big difference. But nothing like what you just created. I miss old school mouses.
Been waiting on this video, I'm going to try that summit cam in a 400 sb with vortec heads
Right on! I plan on using the Sum-1204 with possibly some Rhodes lifters on a 406. Should be a potent street motor
With a 400ci you may want to step up a size on the cam, 45 more ci to fill...
I love these videos! Show the hp when he do any upgrades!
Sbc ls and big block chevy. The king of all forms of racing
Looking forward to the carb/sniper comparison
that would be a nice motor for my s10 build, cant wait for the roller version
Stage 6 pro cam 😎
I ran a 383 stroker with 87 octane on a hot day at the dragstrip to a 12.3 @117, 87 octane on 11.2/1. Long rod, vortec heads. Anyway that is an inspirational build you have there! I am currently building a 327 with 6.125 rods, and 350(6'" rod) pistons, gonna use one of those summit 4/7 cams you used but maybe a little smaller, looking for 425hp in an 86 IROC.
Really enjoyed your video Pat, awesome combination and exactly what I'm looking for, I have Dart SS 165 cfm heads on mine and will be swapping pistons for 11:1 compression. Those numbers are awesome for a budget build, My little coupe only weighs 2200 lbs so even 450 hp would be pretty quick for a street car, thanks for posting, and you have a new sub.
Thank you appreciate the sub! 450hp at 2200lbs will be a riot 🤘🏻
That’s a stout motor, nicely done
Thanks Jimmy!
Try afr 220 and 11.1 and 525 might be possible
Bloodviking
Pretty nice for a low buck 350, I'm building a factory hydraulic roller block to do the same thing. I already have some aluminum heads though. I'm hoping to get 500
Wow! Definitely a sleeper with the factory Vortec heads. The exhaust might be a giveaway though.
I guessed 437 hp and 427 torque I believe. I was off by nearly 10% on the hp! Very impressive! Can't wait for the parts list.
Would also love to see a version for heavier street vehicles. 👍
Dingle ball 2.0. Only 10:1 with less duration but more lift and a roller cam
@@cuttersperformance can't wait!
I have a 327 I pulled from 68 rs/ss camaro with 22k miles on it few months ago. This would be cool setup on it.
❤AWESOME!
Very stout results ! Congrats. I’m going to follow your porting tips when doing my 383 vortec head-motor. Unfortunately they’re Mexico made, which I learned thru you channel aren’t the best performers.
They dont quite flow as good but they crack less
Wow that's definitely the power range I was hoping for in a hydraulic flat tappet. I did however think that it would remain power brake friendly but nothing a vac pump can't cure which then makes it very streetable. Excellent post my dude!💪🏽💪🏽🤛🏾😎🏁🏁🏁
Or even better Hydraboost brakes! I knew the vacuum would be low on this one, considering it has 89 deg of overlap
Just switch to manual brakes. That's what I did on my '71 Camaro. I got tired of dealing with the hassle.
@@Carl_Jr I'll have to look into this because I already purchased cam.
@@steelcitycaprice.899 I got my conversion at Motion Raceworks.
@@steelcitycaprice.899 Can always test with a good sized vacuum can first. Inexpensive, easy to install, and you can adjust the cannister size for your application/brake feel.
Wonder what I can do with my 327 factory forged everyting internally if i put vortec heads on it. Needs rebuilt (was stuck) so like 30 over forged units to come around 11:1 compression with some light ported vortec heads. Was and old boat motor also have a 454 same thing
i want to see what you can do with my lunati cam or the step up from it i may swap to.
my motor is still green and running as good as ever.
Awesome build, let's put it in a car and race it!
Awesome engine. This belongs in a ford mustang or falcon or factory five with a 4 or 5 speed. Then i bet it would run around town and the track and tear it up too. They Roller cam version is going to be quite interesting as well.
Why a ford? Haha but would be cool
Please do a video on breaking in flat tappet cams with todays modern oils.
Almost everyone I know of today has sworn off FT cams due to failure percentages. You obviously haven’t, so please let us know your procedures, and oil recommendations.
I was thinking that might be a good video series. I have a few more flat tappet builds in the works
That is a dandy dyno graph for sure! when can I drop off my heads for porting and valves? haha
Haha no porting services
i have an 880 block your info has really helped i put an edelbrock 2204 cam and did what you said for the lift on valve springs,keepers and retainers. check out my short clip sounds great
would love 300 horse
Very impressive performance Pat! Dyno numbers are great, but I would like to see you drop this engine in a car and make a few passes at Toronto Motorsports Park Cayuga. Maybe something like that Firebird that you used to show at the beginning of the Piss Cutter Performance videos.
My Trans Am will be back! Unfortunately, I put on the back burner the last few years, but there will be videos on it soon
That’s great to hear Pat!
Nice combo: should be happy in front of a 4 speed. Maybe a touch too much overlap for me as a street build, but... soft easy ramps on that should be worry free for a long time. I would be tempted to compare to a 288/294, and get some of the vacuum back, while holding close to the 0.050".numbers - maybe give up 2 degrees.
The roller cam version (dingle ball 2.0) coming up has less duration, but more lift with a roller cam. Should be an interesting comparison
Very impressive what valve springs did you use and I'm sure you had the valve guide bosses milled down also that is really nice that that cheap summit camshaft worked with the howards lifters I have a howards roller In my bigblock 439.
All that info will be in the next video
Great videos thanks. Have a quick question I understand this one had different pistons but with a factory block and rotating assembly is there PTV clearance for a .540-.550” lift cam or is .510-.520” the limits?
Is modeling clay preferable over play dough? Play dough sometimes sticks even with oil.
Its not really about the total lift as the piston and valve are not near each other when the valve is open all the way. I use modeling clay
Thanks
I might use this cam in my 406 🤔
Probably run nice on E85.
Would a set of Vortec 5000/L30 heads offer an advantage over the 5700/L31s with the same port work and larger valves? I would guess they wouldnhave snaller chambers from the beginning and mill diwn wven smaller. Even if they didn't offer more peak I would guess there would be a lot more low -mid range TQ. Similar ro usung a 706/862 5.3 head on a 6.0L in place of a 243/799.
The 350 vortecs have a much better combustion chamber over the 305s heads
Nice! Ive got messaged vortec heads on my 383 making a little over 400hp. Heads flow 225 from .400 t0 .600.
Roller cam, 218 @ .050 with .480 lift on a 108LSA. Heads still have stock valves, i wonder how much bigger valves would help vs more lift (1.6 or 1.7 rockers?)
Love your videos
Bigger valves only work if ported. I typically prefer 1.94/1.6 with porting. As far as lift goes, Ive never seen a SBC lose power with more lift. So some head porting and a 1.6 rocker arm would be a noticeable improvement
Nice engine! Do you think the 4-7 cam design would work with a dual plane RPM type manifold? I know single plane is what you used. Keep up the great videos!
Yeah it works with a dual plane. Something like a RPM Air gap would work good with this combo
Awesome what setup did you use to get that high hp the 750 -850 carb or the sniper and what size was the tb on it
I don’t get how this wouldn’t be good for a heavier vehicle with gears and stall converter if auto? The torque curve was amazing and made 400+ down from 3400.
Awesome! wonder what it would do with a dual plane?
I should have brought one to try. My guess it would gain 15 to 20 ftlbs and lose 15 or so hp
That's a lot of horsepower for what it is, impressive. Great video. I have a L31 in a 2 door 98 tahoe that just has mufflers and a cold air and has pretty good power. I would like to hop it up a little but don't want to lose any low end power,any suggestions?
A mild cam and a tune will help alot
With this cam and paired lifter kit is it safe to break in cam with the sum-174-002 springs conversion??. .
Wow that's pretty good ! Out of a good ol small block! Do you port heads for customers? If so I'm sending you a pair. Great job!
I dont offer porting as a service
How do you think the power curve would be affected by having a dual plane high rise in comparison
Wow i was surprised at the hp mark i used to race circle track in a stock head flat top non stroker motor class and a few guys might have been close to those numbers on hp. Great build
Do you have a favorite intake gasket for the 906 vortec heads
This is the kind of stuff that makes me want to completely abandon building my 2.3 Turbo or even a 289/302 for my 72 Pinto. I grew up with my dads diet of Chevy powered and Chevy V8 swapped cars (other cars and engines too).
I was going to do my best of keeping a Ford in Ford, but this validates the tried and true facts of building power with a Chevrolet.
I guess my Pinto is going to match my late uncles. Chevy in a Ford it is…I’m going to catch hell, but I want to buy, build, drive, blow up, buy, build and drive. All without the costs of trying to make HP with the blue oval.
Can't go wrong with an SBC!
I'm a bowtie guy but I built a 289 Pinto in 1981 and I would stay with a sbf, I was never beat street racing in that car, they weigh nothing, you could get some pretty good power out of a 302, if you want crazy put a 351 Cleveland in it
@@hardtail-gy8dk
My late uncle went down that road when my dad and him were building his 71 Pinto and my dad’s 64 VW bodied/Austin Healy chassis car.
The Pinto had the 302/C4 combo and when I was about 10 years old he stuck a 383/TH350 in it. Like my dad told me then. Dollar for dollar and cubic inch for cubic inch you can buy, find, swap and run into Chevy parts cheaper and more choices available than a Ford - including making horsepower.
That being said… I won’t be tempted and refuse to LS swap it. My dad has enough old dress up parts from the 60’s/70’s/80’s to make a SBC look period correct.
That’s a lot of flow for any sbc cylinder head. That is a lot more than any stock port vortec head will flow, it took a lot of porting to get those numbers.
Be nice to see flow charts at specific lift numbers to compare to other cylinder heads flow.
And compression does a lot.
Fuel injection and computer control makes a really big difference over carburetors and non computer controlled ignitions when it comes to high compression and lower octane fuel.
I would like to see 9.5:1 and run it on pump 93 and see what it does.
All we have at the pump here in Texas is 93, and two stations that have E85. And it’s pump e85, not the good, accurate E85 you buy in barrels like race fuel.
Heads were ported and full flow numbers in the next video. The dingle ball 2.0 is a 10:1 355 with less compression should be a interesting comparison
@@cuttersperformancenice!!
I ran 10.5:1 on my iron head Vortec 383 in my G20 van on Texas 91 or 93 for years. My 11:1 aluminum head 383 in my Express runs on the same fuel.
thank you for the video, would love all the specs, i am looking at a real budget build for a little s10, starting with a 79 350 block.. if you can share the list and part numbers and which carb you feel worked best, also can you tell me any thing about the factory aluminum chevy vortec heads, i can get a set, but i read something about reverse cooling.. not sure what that really means thanks in advance for all the help
reverse cooling is 92-96 LT1 heads..those are different
Awesome results there Pat! Could you please explain how did you port the vortecs to improve the flow? Is it with the stock valves?
These were ported with 2.020/1.6 valve
That’s bad ass for a set of vortecs ! I have a set my self but I would love to see it live when those numbers were made like most would do , also how long do you think the heads would live with out cracking with what’s been done I ask this because I’ve been thinking of have larger valves installed
I usually just go larger on the exhaust valve (1.6) takes alot of porting to utilize the 2.02
Refreshing a ZZ4 short block that i picked up. Vortec heads or the aluminum Chinese heads?? Going in a boat and having a hard time finding good comparison info.
The vortecs are good value if you can find good castings for cheap. If you have to buy new, then the china heads are typically a better option. I ordered a set of NKB eBay heads to try on an upcoming build for more comparisons
Another quality SBC shows that the old shool block is still dishing out reliability and numbers would rather have this than an ugly LS motor
