@@waynetoneseekerandersen2213 My first was a 383. Ask around about machine shops that are accessible to you in the case of an over-bore.

@@soulcapitalist6204 It’s so great for you to give me some first hand advise! Yes I will be buying David’s book. It’s hard finding a machine shop with a clean reputation, since more are likely to complain than recommend. Thankyou my friend
I ordered $5000 worth of parts for my 5.7 vortec build and the very next day I discovered this channel. Needless to say i was able to refund almost all of my parts before they shipped haha.
Hello sir. I am an engine tuner, on Austin Mini and other English cars, my workshop is in the south of France. it is thanks to you and your book that I was able to learn my trade. thank you sir.
David,I've always liked the 421 ci small block chevy engine,this is very impressive, my engine builder here in Colorado built me one with rons porting 18 degree heads,hogan's sheet metal intake,twin Holley Dominators,obviously not a street engine,but it made 840hp,680lb ft torque 20 years ago,he is now deceased, I know there are much better cylinder heads out today, im looking to build another 421 engine,hopefully clip the 900hp mark with a single Dominator, wish me luck
The legend has spoken!I know a good bit but wish I knew half of what he knows.I see all these LS swaps and hellcat motors where they rebuild the motor anyway then fight with computers and tuning and all that garbage and I'm still a firm believer in the sbc strokers matched with the right cam heads intake carb ignition system etc.I believe one of his carburated motors will blow all that trash off the track all day long.Im not worried about building a race engine for the street,I don't race on the street,drop that little 421 in s10 or a Monza or something with a good two speed power glide and some 3.73s or 4.11s and get it to hook up and I'd race hellcats title for title anytime they wanted to!
I remember the days of finding every little trick in the book to make a n a engine perform. Angle cutting heads, head porting, milling, spark plug indexing, bigger exhaust, stepped race headers, tunnel rams, carb mods, gapless rings, more compression, hi octane gas, intake manifold porting. Truck blocks, cadillac 500s in camaros. Then all that changed when forced induction became cheap with used turbos, diesal superchargers etc. We made power undreamed of. 800 to 1250 hp now became fairly easy. This other n a mods take loads of, skill, effort and time. Bloodviking
Terry Walters Racing Engines rocks! I live in Roanoke Va and I take them all my machine work. He has two of my engines currently and has previously worked on at least 3 other engines. Terry and Jack did a turn key, 385 sbc build for me a few years ago. It made 480hp with factory cast block and double hump heads with a 2x4 tunnel ram using 450cfm holleys. I'm currently running it in my 72 pro street Vega. Scat steel crank, Icon pistons, Comp Cams mechanical, flat tappet .555 lift cam. Great people!
Watching you makes me realize I know nothing about building an engine. I’m still watching with intent and hoping things start clicking soon. Thank you for the spread of knowledge
Thanks David for the invaluable content. I successfully built my first engine (10.2:1 SBF 332 ) never dynoed it but I know it’s good. Next build I’m planning a 427 Windsor. Looking forward to all your knowledge to implement in my build.
Great job David! This touches on the possibilities of a total build using DV's science and the right builder. This is exciting! DK, ASE Master Tech Retired.
I did the intake manifold on this build. It was originally done by Wilson and then worked on by someone else before I got it. I had three days to work on it. The apex of the turns was min cross section so I needed to work on taper quite a bit. D.V. asked for a specific texture. I spoke to Terry and we had the idea to texture the outside as well. Manifold was coated inside and out with different coatings. Is it possible the brake specifics have some thing to do with the internal port texture? The plenum got a full rework. I needed to do some epoxy work because this manifold was drilled and welded for fuel injection in a past life.
Check out Speier Racing Heads Burr finish. Ive run his 23 degree sbc stuff for years. Darin Morgin says its the bet 23degree head for sbc on the market! Burr finish is what he did when he fully ported my BMP intake and Profiler heads. 715 hp

Hi Don I have been racing flat track motorcycles since 1969 and have had my own shop since 1980 I build a lot of 450cc singles if I could just stay at the porting bench I would be very happy but being a one man shop it’s a bit hard I’m sorry to say but I just saw your videos for the first time and I sure wish I found you a long time ago I can’t stop watching them thank you so much for Sharing your information I can’t get enough of it hope you have a great New Year and thank you again

That's really potent! I really like the insights all throughout your videos; I even notice things you don't mention and go, "Huh. Interesting." I'm at the pencil-and-paper stage of building a 327cid Motown LS for my '63 Impala. I like the idea of the drop in SBC fit coupled with the free-breathing performance of that LS top end. Might take me until next Christmas to rake together the capital tho. LOL!
Aftermarket sbc heads flow better than stock ls heads. Don't saddle yourself with the oddball block and specific intake design. A regular old sbc can run great. You can use aftermarket multiport fuel injection to get great fuel economy too.
@@EricErnst Thanks. I was kinds still on the fence about it. The original 327 & Powerglide are long gone & I was mulling a remotor back to 327cid, but more formidable than OEM. Kind of a purist thing, 'cuz it's badged that way. I bought it with a 350 running Vortec heads, street-strip cam of unknown origin, gear drive, MSD 6A ignition, Edelbrock RPM Performer intake, 750cfm 4160 list 3310-6, kitted TH350 with a 1500 stall converter, and 3.55 rear end. Bottom line: I've got lots to work with & just really need to ice up a plan for what I want this car to be.
@@darrinrice367 I was pretty excited about the motown LS block when I first saw it. The dart blocks are motown for SBC stuff and Warhawks for LS stuff. I think they missed a great opportunity to call it a Mohawk block. I think their biggest drawback is that the intake has to fit LS heads and keep the distributor hole. That means the intake manifold selection is VERY limited and specific to only dart castings.. which are probably in scarce supply and very pricey. Like I said, I loved the concept of it when I first saw the motown LS stuff. I've got a pair of trick flow super 23 175cc heads on my 350. They have tiny 56cc chambers to bump compression. They flow 242cfm@.500" and 245cfm@.600". Through 1.94 valves. With tiny 175cc runners. Port velocity is high with the tiny ports. LS1 heads flow 237@.500" and 243@.600" wirh a 200cc intake runner and bigger 2.00" valve. And a 67cc combustion chamber that lowers compression ratio. If you can swing it, get afr cylinder heads they offer a 185 and 195 option and flow much higher.. along with their higher end stuff. The trick flows that I'm running will support ~500hp at the crank depending on other parts. That's plenty for a street build like your 63 impala. I've got a baby roller cam with very short duration that puts peak power around 406hp@5500 rpms. 450lb-ft@3000 Top of the page cam. 202⁰/212⁰@.050". .585"/.581" lift. That's 1⁰ off of the stock 400hp LS2 camshaft of 203⁰/211⁰@.050" but it has lower lift of .424"/.421". I can bring the idle down to a lopey 400rpm on my holley sniper unit. I usually have the idle at about 750 for street driving, a little closer to my converter. That's all with simple bolt-on stuff on a 1990 350 block. You don't need a trick aftermarket dart block for your setup. Unless you want to be the only guy on the block with one at a car show. Good luck with your build!
I really appreciate you sharing your knowledge/experience and stories as it makes me realize how much I really don't know. I wondered if you ever done any work on the Chrysler polyspherical cylinder heads of @1957 ?
Thank you for the video stout numbers you have done. You have done several Chevys and Ford engine builds but would you do a Pontiac engine build?? I know the Pontiac engine is much more expensive to build but I would like to see how much you can rip the 400 cid engine.
Sorry DV but not a street motor. Dam good TQ and hp . Killer setup. Love it. I really can’t see driving this down the road at those kind of rpm. Would be a really cool car ( nova) 6 speed,4.56 rear end . 6,000 TQ? Wow. I can’t get that out of my mind winding a motor up that much. Most of the time I run 2200 to 5000 on the street. Would be cool to have a setup like that but man I am going to get to know the cops! Lol ! Can you do a mopar La like that? Nice out of the box. You have a really good Xmas and new year DV and hope to see a killer 318 coming up soon. Good luck on the project!
I would disagree a low gear makes it get into a high RPM quick more like 6500 RPM light to light 456 gears or lower the 12 -1 compression for sure is not a 92 octane set up lol a street set up at the most would be 11-1 more like 10-1
@Darrell Somers 11.25:1 on a pump gas premium LS7. Actually mix 50/50 premium and mid-grade (89 octane mid-grade/93 octane premium) for pure highway driving. Enough cam duration will lower combustion chamber pressure/dynamic CR. 43,000 miles on it since 2014. Drive it to Florida from Michigan every Fall, back to Michigan every Spring, no issues at all......
DAVID IS A GOOD SOUL , THAT HAS ALL MY LIFE BEEN PASSED HIS WISDOM TO THOSE THAT WHt yo gain knowledge about the correct thought process of gaining power. I'm grateful to know the wisdom back in history buying his various books. Pay attention to his words for they will get rid of various false teachings. His words are as gold,in the bank.

I'm watching your build now I build a 700 horsepower 383 stroker for my 69 Chevelle and I'm also going to be feeding it to 350 shots of nitrous all built at home by me the only one that has ever touched this car nice build
Great video as always! Is there a forum or email where someone can ask questions about their build and why it may not be making as much power at the proper rpm?? Struggling with a high compression, big cam, big head, 383ci SBC. Won't make more power after 6500rpm and is only making around 550hp maybe!! ??? New to SBC engines and have put a lot of $$$ trying to figure things out so any help would be greatly appreciated!!
If you were gonna build a engine that was gonna be a work horse in a plow truck, would you build it like a race engine? My boss is 85 years old and he bought a 72 chevy with a stock small block 350 off the show room. He's been running it as a farm truck, plow truck for all these years and she's still pushing snow. I've got a 78 bronco with a worn out 302 that I would like to turn into a plow truck. I guess I'm wondering how do you build a strong engine, maybe not necessarily a fast engine?
This is the man who got me to build my first small block chevy! With a book!
Which book? I'm doing my first soon
He is inspiring me… but I am unsure if I should… would love a 383 for my 94 k1500

@@milojanis4901 yep, cam duration will help Lower compression. Long duration cam in a motor with only 9.to 1 com will feel like a sick dog.
David, I would like to see a build using AFR's 245 23deg sbc heads.
DAVID IS A GOOD SOUL , THAT HAS ALL MY LIFE BEEN PASSED HIS WISDOM TO THOSE THAT WHt yo gain knowledge about the correct thought process of gaining power. I'm grateful to know the wisdom back in history buying his various books. Pay attention to his words for they will get rid of various false teachings. His words are as gold,in the bank. God bless david now and forever
That would be a perfect engine for my Corvette
Thanks for the 421 sbc there not much out there for info would like to see one of your videos on this engine like you did on the 383 thanks
I’d love to see you build a MBE top end sbc and see what you could get out of it
It would be nice to see more mopars
I’m the man at logging on at the last 2 minutes 😂
I'm watching your build now I build a 700 horsepower 383 stroker for my 69 Chevelle and I'm also going to be feeding it to 350 shots of nitrous all built at home by me the only one that has ever touched this car nice build
Great video as always!
Is there a forum or email where someone can ask questions about their build and why it may not be making as much power at the proper rpm?? Struggling with a high compression, big cam, big head, 383ci SBC. Won't make more power after 6500rpm and is only making around 550hp maybe!! ??? New to SBC engines and have put a lot of $$$ trying to figure things out so any help would be greatly appreciated!!
For a marine 454cbb to get over 700hp line naturally aspirated engine. what you recommend, in parts?
Thank you for the video
can I change hydraulic lifter, to roller hydraulic lifters on a new cam, on sb-350 chevy ???
Is there a build sheet for this? I watched the whole video but did not get cam specs or part number of heads.
Dave
Do you have any plans to do a video on hp tips on vintage vw's Beetle type 1 engines?
If you were gonna build a engine that was gonna be a work horse in a plow truck, would you build it like a race engine? My boss is 85 years old and he bought a 72 chevy with a stock small block 350 off the show room. He's been running it as a farm truck, plow truck for all these years and she's still pushing snow. I've got a 78 bronco with a worn out 302 that I would like to turn into a plow truck. I guess I'm wondering how do you build a strong engine, maybe not necessarily a fast engine?
We can do that - remind me about March that I said we would!
Power is in the heads always will be that's why the hemi was so good of coarse it has to be strong or it won't stay together
Good information.
incredible very impressive
Is it possible the HP at 6400 rpm onwards, is a little problem with Pushrods and Valvesprings... Valvetrain... ???
Do you think it’s possible to see 700+ hp out of a SBC under 400 CI with a 23 deg head?
That is over 1.75 hp per cubic inch. Highly unlikely, in a NA application.
Hey John I did get 900 hp from a 427 with a 320 cam at 14.1 comp on hi test back in the 2010. N.a. 8000 rpm.
Wow, impressive
I support this content.
thanks david
Great info
Hope that fits under the Christmas tree .🏁🏁
I'd like to see this with a small block mopar.
Awsome I've said for years big power is in a chevy small block
INSANE #’s!!!! N/A are you kidding me.Peak torque on A single plane,,,there goes that theory 😂😂😂.
have you experimented with E85 to avoid the need for race gas?
Yes.
can you do a 10 degree sbc test
DV, I'd love to see how you would build a DZ302 Cross Ram transam engine!!!!! Future videos???!!!
