Instead of a shoot out, stick with the vortec. Put the iron heads back on and keep raising the boost. Prove what you can make on a budget, and how far you can push it..
Probably not that much HP, the insane TQ it would make would blow it up before it made anything impressive. It would need porting, and IIRC Engine Masters pushed stock heads to mid-400's. It would probably need a short runner manifold to shift torque up high to keep the rods happy.
I would like to see this... possibly without ring gap to see how much you can get away with.. for people that have their engine already in their vehicle....
I would love to see the “shoot out”. I have always wondered how big of a difference the sbc intake runner volume, heads, compression ratio, and oiling system would directly affect engine safety to power compared to the ls’s setup, Obviously if you ran the steam port setup with bigger rods on the ls you might be able to pull out more power than the sbc, but it would be awesome to see a price to power analysis shootout between old and newer tech!
Engine Masters did that very thing. Just opened up ring gap. Made over 700hp (25 psi) when they ran out of smaller pulleys for the centrifugal. Held together.
98' L31 Silverado. Changed the fuel injection to ramjet, comp cam and a d1 procharger made 380whp 440ftlbs. Took the procharger off and installed a turbo. At 12psi is made 430whp and almost 500ftlbs. Fun truck.
Given a proper tune - with absolutely NO detonation - the power levels possible on junkyard leftovers without breakage might amaze a whole lot of people!
@@dutchvanderlinde658 I have videos of it on my channel. I did not gap the rings, we took it out one cold evening and I believe it pinched a ring land. Only one piston was broken along with the connecting rod. Stock rotating assembly.
Yes, you should do this! I responded to someone on one of your other videos that I didnt think you could get 1000 hp out of a vortech with stock heads, and I doubted the short block would hold up. You responded you thought it could happen with no more than 19 psi. Id love to be proven wrong. Would be really cool to see it happen!
Great content Richard, I have a vortec 350 in my garage needing some attention and always thought a turbo set up would be too much, but since you showed us that it's not I may build it similar to what you had in the video. Thank you for sharing. A comparison video to the OG SBC would be enjoyable to watch. Take care.
I'd be prone to want the LS just to know I've got a block I can't break (excluding rotating assembly failures that window it anyway) and more modern heads. A test to prove I'm blowing smoke up my own ass and an SBC can do more than I need would be awesome to see though, swap the cam and valve springs, gaptize them, throw on some decent head gaskets and head bolts, and let 'em go until one goes bang. One potentially neat twist: instead of turning up the power level until something blows up, maybe try setting an arbitrary power level both engines must meet (say 650HP at the crank for a comfortable 500+ at the tires) and cycle the engines between peak torque and peak horsepower until something explodes. Sort of a road-racing centric simulation to see if the low buck bangers have a chance in hell of surviving in a context like that.
I think if they were both crank sensored, multi coil and fuel injected that sbc would surprise some folks on how well it lived with decent timing control and fuel control.
Recent machinist channel site, made a valid statement on the 2 vs 4 bolt arguement. When was the last time you've seen a crank thrown from a block. While a 2 bolt, is stronger, due to it has more clamping force material.
I would love to see a big bang L31 (5.7 vortec), I have always thought the old sbc is a great platform and doesn't get enough love now with the ls and the lt motors. I would love to see how much a stock short block can take in comparison to the new generations of small blocks from Chevy. I would also like to the the shootout to see the difference between the generations.
Yes do a sbc vs LS turbobuild off. I have a 350 short block with 550hp topend, and twin50 mm dna motoring turbos, in my 1991 formula, built for 425hp, but I built it right, it may make quite a bit more. I haven’t tried it yet, but I will soon. I bought a L78 bbc that I will boost too in the future. I like to watch your videos and pick up on some of your techniques and build similar kind of motors. Thanks for your videos and all the knowledge you pack into these episodes. I’m Keith Houda from Chicago land south suburb, don’t work too hard and stay safe!
do a 92-97 LT1 Vs the 5.3 might be a better match Especially since the Lt1 heads are aluminum and can take a good spring upgrade with no modifications If you dont wanna mess with the optispark just run a Carb Lt1 intake with distributor and blow thru carb
an LT1 will probably cost you more than a junkyard LS and is a LOT more rare. Then you have to buy a special intake in order to use a carb...and then replace the optispark..those two items alone will cost you more than just getting a JY LS lol.
I have done this before running 15psi on a bone stock lt1 for a few year's. Works great and they are cheap. Just picked one up about a month ago for 100 bucks complete. I have purchased one in the past for 200 bucks and it was a 4 bolt main. I've made over 800hp to the tire on mainly stock parts and stock t56. They are better than what most people lead you to believe.
Thanks Richard! I commented a while back asking you to test one of these old mouse motors to settle a debate with a stubborn co-worker. I was surprised also! I'd love to see a shoot out and thanks again for taking the time.
Please please please do this with the Vortec heads. I saved this video as soon as you said you bought a vortec motor.... then my excitement was completely taken away with the other heads. Great video, now I'm hoping for the vortec comparison. 😃
Yes, also do one with an older sbc, some of them came with forged pistons and cranks. 010s have been legendary for years but alot of people nowadays claim they are a myth. Late model vortec will be interesting too.
Hey Rich - when are you going to invent a tool to trim ring gap with the pistons still in the cylinder? You're the man for the job, we know you can do it; and save all of us cheap skates the effort of tearing down JY garbage just to fix some ring gap...
And on side note Richard thought your response to the rave music was hilarious!!! Amazing how people get the moment your like of being something they dont results in there negative insinuations of (RAVE MUSIC) smh i rock that shit too especially during on long trips driving keeps me up and alert when otherwise end up falling asleep. 😴
I have a question, is “boost” an accurate way to measure how much air is being forced into the intake? If I put 10cfm thru a drinking straw it will be at a high pressure, but the same 10cfm thru a fire hose will be at a lower pressure The actual amount of air will be the same but the pressure will be different, so is there a more accurate way to describe the amount of actual air being forced into the intake? Possibly cfm? That would be an accurate number, equal for the gen 1 vs LS comparison and eliminate the whole “ how much boost you running” debate , I realize that you discuss this but it’s still somewhat misleading to some people that think more boost is always good, more cfm is really what we are after
you should do it, but even as a gen 1 fan, I can't see the mouse coming out of this and looking good. In fact I would bet that new painstakingly built Gen 1 motors will start pitching rods into the wall long before the junkyard LS motors even vaguely protest. The "put an LS in it" crowd are often annoying as hell, not seeming to understand that many of us consider just dumping an LS into something misses the point, even verges on 'cheating'... but even if I love the idea of taking my 50s era technology and turning it into a powerhouse through meticulous prep and research, and careful technique? I can't deny that the LS motors are what the sbc grew up to be. And like an 8 yr old wrestling with dad, there will be no contest. No contest at all.
Richard, Thousand of boaters would love to see what you could do with the mercrusier 350 mag engine. There is no videos on these MPI motors being upgraded. I think this would be an awesome addition, not to mention this should add 50 to 100k subs. The 5.7 motor has been put in millions of boats.
@@richardholdener1727all mpi 5.0 and 5.7. They have been the same 300hp for like 20yrs even when they went to fuel injected. I talk to hundreds of owners and they are all looking to boost power without breaking the bank. Now they are just starting with the new 6.2
Yes do the shootout. I’d also like to see what mods are needed to run the vortec heads and weather it’s cost effective or is a budget set of aluminum heads a better choice. I’m also curios to see how they would respond to no mods, junkyard fresh and just slap on the turbos, intake and carb.
This is cool. I come from the sbc world. Ran them for years. I think your at a safe limit in power here. Any more your asking for trouble . Now think a fuel rail system and ecu controlled you could push it farther. Having control over timing threw out the rpm range would help make it last.
You need to build an engine for donut media. Build relationships with other you tubers with millions of sub and watch yours go way up!! Your on to something here with these awesome tests!!
Just picked up a 99 Vortec 350 for free. Going to be doing the same mods as the test motor minus the ported heads. So it would be cool to see the comparison of the LS.
Do the test with old vs new on boost I just have to know lol . You do the best testing and give some of the best info and it has helped me with some of my builds
Cadillac secrets, Hey guys take a 472 cad engine and use the 120cc heads and check out the massive lift between the piston at TDC and the valve head. It's surprisingly great. Bloodviking
Nice. I would have liked to see cam upgrade on vortex head , then boost. Continue with cam pluss new head test, then boost. But like always, great vid.👍

If you think the old school SBC likes boost enough to make it worthwhile, then go for it Richard! It will make good content to see how much better the LS is. Are SBCs even cheaper than 5.3s and 4.8s? Maybe the fair fight is a 350 vs. a 4.8?
SBC verses a gen 3 LS 5.3, both with SBE, use aluminum heads on both engines that flow similier, use a similier camshaft (both engines with roller lifters and 230-240 duration ) and then keep increasing boost. The only disadvantage will be the 24 cubes the SBC has over the 5.3, but it would be interesting to see the max boost the SBC will last to.
@@richardholdener1727 That should be a great comparison! That way it levels the playing field for the smaller 5.3. compared to a 5.7. Thanks for sharing dyno testing that would have been regarded as top secret in past years.
A stock block can handle about 659 hp. You should still beef up the block with fill and cast iron heads, not aluminum. It keeps the block stiffer and stronger. Bullet steel main caps on all of them and a stud girdle. Maybe it can take 750 if you don't rev it high often. Bloodviking
I would honestly be interested in seeing a sbc vortec vs a sbc non vortec with oe hesds and see how much a difference in power there is when adding boost. Thank you for all of the awesome and interesting content.
They are good heads for 400-450 na horsepower. Beyond that aftermarket makes more sense. They are prone to cracking, thin casting. For a street deal with mild boost they are decent. But not worth investing money into when out of the box budget aluminum heads flow better, capable of more lift. Raising the boost isn't good. What he can get away with for 7 seconds on a Dyno is not what will last on the streets with 185-210° coolant temperature.
Dang I have a GM goodwrench crate 350 in my 64 impala. I put the fitech ultra ram on it. Was thinking about twin turbos next winter thinking I cold get like 450hp out of it, but got damn, 600. Gonna need disc brakes too to reign it in.
Yes that shoot out would be awesome... Old vs. New, Father vs. Son, SBC vs LS. Hopefully give me more incentive to keep my SBC and throw a turbo on it as opposed to get rid of it because LS
Just swapped out a warn out 305 with a carbed vortec 350 in my boat and what a difference. Really wanted to do a ls but didnt want to buy new marine exhaust manifolds.
Definitely do the shoot out we know what will win but by how much is it as big as people think. I really wish you would have done it on the steel heads as most people with junkyard motors can’t afford to just go buy aluminum heads. Would have been nice to see you make them work or not to help people decide just my opinion
Grab an EFI connection 24x reluctor wheel for the 350 Vortec and slap the LS ignition setup on it so that it has good spark energy. I made the upgrade myself for what the reluctor wheel and cheap coil brackets cost. I had then LS coils kicking around the shop.
Love to see a shootout old vs new. Think the ls will be king though. Better efficiency all around, reduced valve angle in the heads not to mention the port and chamber design, smaller ring pack for reduced friction.
Does this man ever sleep ? Thanks Richard for helping my addiction to horsepower in these times with all the content
Sometimes i think this guy comes over every night to my home, every night i see a new video
I don't know, bit I'll bet you money he dreams about camshafts and boost.

If you think the old school SBC likes boost enough to make it worthwhile, then go for it Richard! It will make good content to see how much better the LS is. Are SBCs even cheaper than 5.3s and 4.8s? Maybe the fair fight is a 350 vs. a 4.8?
The weak parts of a sbc stocker are, pistons, rods, hi rpm on a cast crank, the blocks stock mounting area.
Tip, All cylinder heads are great once you run power adders.nos, forced induction, etc
SBC verses a gen 3 LS 5.3, both with SBE, use aluminum heads on both engines that flow similier, use a similier camshaft (both engines with roller lifters and 230-240 duration ) and then keep increasing boost. The only disadvantage will be the 24 cubes the SBC has over the 5.3, but it would be interesting to see the max boost the SBC will last to.
I'm thinking stock heads on both
@@richardholdener1727 That should be a great comparison! That way it levels the playing field for the smaller 5.3. compared to a 5.7. Thanks for sharing dyno testing that would have been regarded as top secret in past years.
A stock block can handle about 659 hp. You should still beef up the block with fill and cast iron heads, not aluminum. It keeps the block stiffer and stronger. Bullet steel main caps on all of them and a stud girdle. Maybe it can take 750 if you don't rev it high often.

You made me love the thought of a sbc again.
Never forget. 😁
I would honestly be interested in seeing a sbc vortec vs a sbc non vortec with oe hesds and see how much a difference in power there is when adding boost. Thank you for all of the awesome and interesting content.
Pre vortec's have torque, but really lack higher rpm horsepower.
They are good heads for 400-450 na horsepower. Beyond that aftermarket makes more sense. They are prone to cracking, thin casting. For a street deal with mild boost they are decent. But not worth investing money into when out of the box budget aluminum heads flow better, capable of more lift. Raising the boost isn't good. What he can get away with for 7 seconds on a Dyno is not what will last on the streets with 185-210° coolant temperature.
@b.c4066 thank you that makes sense
I like that I learn something from all you videos.
Yes yes and yes you definitely need to do it
Dang I have a GM goodwrench crate 350 in my 64 impala. I put the fitech ultra ram on it. Was thinking about twin turbos next winter thinking I cold get like 450hp out of it, but got damn, 600. Gonna need disc brakes too to reign it in.
Yes that shoot out would be awesome... Old vs. New, Father vs. Son, SBC vs LS. Hopefully give me more incentive to keep my SBC and throw a turbo on it as opposed to get rid of it because LS
Just swapped out a warn out 305 with a carbed vortec 350 in my boat and what a difference. Really wanted to do a ls but didnt want to buy new marine exhaust manifolds.
I would definitely like to see that with stock heads and intake only valve spring and ring Gap and maybe camshaft only
You can't get enough injector to allow use of the stock 96-2002 l31 vortec intake.
Hi Richard, big fan
Hellll yeah this should be good you are the man richard
A twin turbo sbc stock block gets overwhelmed quickly at it limits especially when running high boost. Doing this to a bbc is wiser.
Bv
Yes !I cant wait to watch this awesome shootout you are planning..
I would like to see a 351w turbo vs a 350 turbo I think that would be interesting
Engine masters did a 351 vs 350 with identical parts and the motors made the same power. So with boost it would be the same.
Please take us shopping at the junk yard
Definitely do the shoot out we know what will win but by how much is it as big as people think. I really wish you would have done it on the steel heads as most people with junkyard motors can’t afford to just go buy aluminum heads. Would have been nice to see you make them work or not to help people decide just my opinion
Grab an EFI connection 24x reluctor wheel for the 350 Vortec and slap the LS ignition setup on it so that it has good spark energy. I made the upgrade myself for what the reluctor wheel and cheap coil brackets cost. I had then LS coils kicking around the shop.
Your videos are awesome man. I have an idea/request: can we get a video about setting up the holley dominator carbs?
take out of box and install-or watch the recent video I did with Steve Brule
Love to see a shootout old vs new. Think the ls will be king though. Better efficiency all around, reduced valve angle in the heads not to mention the port and chamber design, smaller ring pack for reduced friction.
Yes. Lets see what a 383 stroker with good aluminum heads and s480 do compared to the ls.
