The engine sounds really healthy! I am building one as we speak. 383 stroker. I'm waiting on parts atm. Mine is closer to 11:1 so it can be streetable as a weekend warrior/street truck. I hope mine sounds half as good as yours and it starts up perfectly like yours! Great job
@@rtkl13it wont rev any slower with a clutch assembly and a transmission tied to it. You think your proving a point but your just proving how arrogant you are. It MIGHT have a different throttle response slipping through a converter on an automatic trany but the difference is marginally noticable.
@JBeamGT3 I wasn't trying to be arrogant I was pointing out a small change that can happen. A drive train in general can absorb as much as 20 % but to go to that response it shows how much your douche ass doesn't know about any of it
Wow! That is absolutely amazing. If you are a shop, I might definitely be interested. I’m looking at replacing my 355 and was considering a blueprint 427 small block.
@@NRJracing I do the same...even clutch, pp fw assy that "neutral balanced and dont need it"...sure makes a diff Real stout sbc, built a very similar 383 sr numerous yrs ago remember for yrs noone could get the Probe domed forged pieces anymore.
Probably not a big deal, because this engine is for racing, but an aluminum heat shield around the starter will make it last longer and still keeps the weight down.
With the money to spend on this, I'd go with a Bowtie block for the horsepower along with diamond pistons aluminum manifold stage 2 mild cam upgrade then efi it.
i used a bowtie block on a 400 that i built around the same time as this one, nothing bad to say about a bowtie but this block was outfitted with billet splayed caps and is much stronger than a typical 4 bolt bowtie, in fact if i built this engine with said bowtie im not sure how long it would hold together consistently spraying it with as much nitrous as this one is currently running. It would be fine naturally aspirated but with the kit i would not be confident in the caps on the bowtie
I hope he gets a good laugh at this he just explained how a mere 20 lb converter doesn’t do shit when it’s pushing out that much horsepower. If it does you got a bigger problem
Absolutely love solid roller cams. If you're going to build a race engine, just can't understand why anyone would go with a hydraulic for the strip? What fuel are you using with the 12.5:1?
Or a 454 out of a 70 chevelle the 500 hp factory one. Stroke it out with solid rollers, n.o.s. , and twin turbo's tell me when your done. Or start with an Class A Rv 454.
I may be wrong, but it looks like there's a trend going back to the old gen 1 sbc! I don't know if the LS platform has been exploited or if the gen 1 sbc still has a lot to offer! There's even gen 1 blocks that use LS heads!
A motor thats mass produced for 40 or so years will never die they are pretty damn hardy motors i race the hell out of my 355 with afr aluminum heads 0.30 bore and had the crank shaved down some and had the machine shop balance the set put a lunati flat tappet in it the voodoo cam with a dual plane intake a a holley 750cfm double pumper that thing scoots in my stepside truck
Out of the box stock vs stock the LS has much better head flow. But if you are upgrading anyway, you can buy SBC heads that will flow a lot. The other thing the LS has is the 6 bolt cross bolted mains, they hold up pretty well to 10 lbs of boost with no modifications. If you're building something up that's completely custom top to bottom, you can make just as much power with an SBC as you can with an LS, inch for inch.
I’ve done a couple 396 smallblocks’ used older high nickel 010 blocks had billet caps put on not splayed just billet with studs, first was 4.030x3.875 and the last was at 4.060x3.875 which was actually 401ci, lot of weird looks when you tell someone its a 350 block but you turned it into a 401 😅 they make really good torque, an absolute blast on the street but never felt comfortable turning them up past 6,500 but that torque was always falling off by the time you get around 4,200 or so, typically shifting right at or just before 6k .. pump gas, alum. Heads, hydraulic roller, airgap intake on both, Haven’t done one solid roller w/ single plane but as I was just mentioning, don’t really want to turn one that hard anyways so I probably will never do it.
Next up is a destroked big block at 447ci will be gm block billet caps, 3.760 stroke lightweight crank and 4.350 bore (.100 over) massive dome custom pistons on 6.800 rods. Will be a 14:1 alcohol motor solid roller would like to see it turning 8,200-8,500 there will be a video posted in the next couple months of the entire build and actual dyno testing my main project currently costing me a lot of money but will be worth it
I just went to JEGS today and got me a 750 brawler I got it put on oh 73 400. On building please erase q750 click Beetle on my 383 it's not quite as much compression as you're running mine is a 10.8 to 1 yeah the year sounds pretty nice did you get the dino your motor that would be a fun one to take down the track have fun later bye
It’s just got a single pumper brawler on it in this video, it’s in the car now with an ATM full race billet 950cfm mechanical double pump on it. I use this brawler to run a lot of engines in, you’ll see it in a lot of my videos, it’s just a really reliable carburetor to bolt on and know it will fire and then jet and mix from there just to get some run time on these motors before they go out.
I have a sgi block gm goodwrench 350 MD i purchased out of a wrecked c60 big truck wirh 2800 original miles. Ive wondered what the "MD" or sgi block has to offer but haven't tore into it yet. 4 bolt? Nitrite crank?
Just a whole lot of blah blah about 300hp my friend good block to work with otherwise it’s a just a 350. 4 bolt & nitrite crank regardless not benefiting you performance wise and honestly not any more reliable than a 2 bolt with a standard 442 cast crank. However you can build a relatively nice motor if you go to a good set of aluminum heads and a hot camshaft I have built many 350’s stock shortblock with a good top end and a good camshaft, however you still are only looking at around 400hp +/- at best people like to spit out completely fictional numbers on their 350 builds but I’m here to tell you I’ve built 350’s on every level from bone stock to high compression high rpm combos and 400’s is about as good as it’s gonna get with stock rotating assembly and without getting completely unreasonable with it which I would never justify other than to satisfy cubic inch restrictions depending on which facet of Motorsports we are talking. Personal opinion?: I no longer find it worth it to upgrade a 350 beyond a good sounding camshaft on the initial build, otherwise I tell my customers just to go to a 383 you will never build a 350 that will satisfy you like going from the 350 to a 383 will.
How about you guys build up a small block olds motor with the use of Big block olds heads and then use the a 350 Oldsmobile motor that was a diesel motor block 350 like that mondello performance in California builds up with a big block olds 425 crank shaft and use the factory high performance camshaft that was used in the past before they used roller cams I've gotten good performance with a build up of my own with the use of the 1970 350 small block olds motor and the w30 Cam shaft and use of the w30 headset the letter c casting heads and the performer rpm intake people who need to take notice of my own personal Creation maybe some one who is an motor enthusiast can tell me about how much torque and horsepower that combination makes I've already built it and driven it with that in a 71 Oldsmobile 442 just looking forward to seeing how much horsepower my combination puts out in curiosity
quick question for ya i have been looking for an intake manifold stud kit and noticed you had studs for the intake! wondering if you had a part number or any leads it would be much appreciated
It’s got an automatic behind it now 2spd Glide- converter flashes like 4,900- shifts at 7,600 . But yea, the day it was on the stand it had a 168t flywheel on it and it turned up like 7,800ish couple times no sweat lol
@@joshkeasler512 nice i just did a 377ci blower motor for my dads last car 4.155 bore 3.480 stroke and that think will turn up to the moon but got the limiter in the mid 7’s so it will survive for a while 7,500 rpm with 12psi and 377 cubes
