- In this, part 2 of episode 22, DV goes into details on how to make $20,000 worth of HP & Torque for about $5,500. This is the 383 that powered our very much low-buck racer that was just a smidgen slower than the series champs record setting $47,000 car! Here's a point that you should not overlook - most of the moves DV talks about are relevant to almost any V8 build!

Beastly build. Easily outperforming anyone elses 383 builds. Back in the day David used to have a paid service, where you could ask his advice on a build, and he would detail the build for you. He gave me a Chevy SB 355 cid build that made 525 hp on 93 pump gas. He specified everything I needed; Crank, AFR heads, cam specs, etc. The component build was reasonably priced for the power output. This was back in the late 1990s and early 2000s. He never disappoints based on my experience. I also built a 400hp vortec heads Chevy SB. I literally built the engine using one of his published books, which I still have. When I was done, it started right up and shortly there after lit the tires down the street.
Would you happen to have the title of the book? I’m building a vortex right now and would like guidance to known power

So sorry about your loss. You are the most informative. TRUE Info on the web. Keep up the good work.
Thank you David for all your years of knowledge you are sharing with us. I would love to see more 383 tips being that more people are going this route instead of building 350s.
Appreciate all that knowledge you have shared.
I've been using his cam specs for my 383sbc builds. They're spot on! Its no doubt you have to get that right. The power curve hits similar to my 2 stroke shifter karts . The only complaint I have is no street tire will survive.
Loved the detailed parts layout and description. Makes it easy to replicate
Absolutely great video David, I watch all your videos and have all your books. Please keep up all the great work!
Thanks for all this info David I am getting ready to redo a 383 that me and my son built about 25 yrs ago and want it to really turn on when it’s done . This info from you is priceless to a guy like me so again thanks.
Perfect format. Very informative.
*Sorry for ur loss! Thanks for sharing your life time of knowledge*
Great information. Building another currently with a Holley EFI…getting out of touch with tuning. All street, my track days are behind me but the wrenching never left my hands.
All solid info. I'm positive I'm going to the cam video next. Thank you for sharing
Sonic turbos are my go to mufflers since I seen the article a long time ago. Even made a noticeable difference on my 94 Cadillac STS
Thank you, David, a lot of great knowledge shared! I was surprised to see the specs on the comp cam used at the end was on a 110 LSA. Especially after all of the talk using a 106 or 107 LSA. Also, I’m a little surprised to see that the majority of questions in the comments have not been addressed. Thanks again for sharing your wealth of knowledge.
106-7 lsa cams unless very small are a pain to live with on the street.
LIke 108 for hot rod stuff and 112 for drivers
Awesome stuff ,,thank you,,I'm building a 3.75 stroke Pontiac, I feel all these principles will work,,thanks again ,
Motor T USMC U RA!!
Thank you for this excellent content. It is very much appreciated.
One trick I did was on a spacer on a 400sbc. The dual plane intake was an old Eldebrock CP 3x (number may be incorrect). It worked very well. I went to thinking a larger intake plenum would help, so she received a one inch spacer. The bottom end didn't change much but the top end was WOW. I then cut notches on front and back of the spacer and fitted 1/4 inch aluminum strap and epoxyed it in for a devider to make it a true dual plane with a larger plenum. Drivability was very crisp. Once on a remote road I gave her a solid launch. I could very much feel her become much more of a devil than she ever was! Stock style and stall conver launch (1500 rpm) to 5500. What a monster!

The cam is Crane HMV272-2, flat tappet hydraulic. Smooth stock idle and 7mpg better than stock. She pulls paste the rated 5500rpm rating. Of course, the valve train was matched to the cam specs.
Mikel
C3BX Edelbrock is a badass intake! The runners are massive! So big in fact that an HEI will not fit unless you grind a bunch of material off of it.
Thanks for the write and info.
Cheers!
@@merccrewlcab2385 Correct. HEI will not fit this intake,I I ran the point ignition. Also blocked the oil fill bung with a freeze plug since I used valve cover oil fill.
@@mikebrooka9395 Cool!
My son and I have a few of them!
@@merccrewlcab2385 cool beans!! Rare to find only one much less a few. Congratulations!
Always good videos, good advice, good tech info
David I had to use four spacers on my cadilack 472 just to get the linkage to cleared using a elderbrock carb a750 cfm I did not have the kickdown adjusted but that car had outstanding gas milage and worked quite well
Speedtalk huh. Yea. Haha. I don't always agree with you on there, but admire your heart, and strength when people come in haughty and proud. It shows your confidence in experience. I am sure of who I seen , he uses that lingo.. but you never have to give much drama if any online. That's admirable.
Wow your vids are great subbed and looking forward to my first book of yours!
Great video David. I have a 406 block I’m planning to build in about 12 months that will go in a 1980 Corvette. I haven’t built a performance engine since I was a kid and those were 265’s and 283’s so obviously it’s been awhile!
I still build 283's for fun!
Thank you for such an awesome place to get proven info that is helpful. This is the only place that I feel like I can trust to give correct facts about engine building. Thank you David for all your help, have you done any work with the 283 sbc.
You seem to have a wealth of knowledge to share. Very informative.
Love the knowledge. My old school brain can understand the information as presented. I would like to know more on building when using factory Fuelie(1.94 & .02) heads. I want everything to look as original as possible. You know, a full out sleeper . Sorry for "our" loss of your partner.
Thanks for sharing the knowledge.
Thanks for your infinite wisdom and knowledge that you have inspired me to try to build an
engine, even though I don't have a car or an engine at this point, but it sounds like a lot of fun . I think I find an old station wagon keep it stock looking and build a sleeper . Thanks for sharing . Extremely sorry for you losing your best friend , I've lost a couple friends recently as well . I pray that you know Jesus Christ, And I pray for you and your family in these latter days .
Dudes a G. Love that following his rules. My 4000 dollar 350 build made 45hp more and 25lbs more with a broader curve than an 8000k professional build motor.
King David’s (Beastly 383)
O’ I saw the video where your old buddy would knurl pistons.
The Knurled pistons does the same thing as the pistons in your Beastly 383.
Controls the oil against the piston skirt and cylinder wall:)
Plus gives a path for the break in grit:)
this is your best video mad up to date, LOVE THE CHANGE, WOULD LOVE TO HAVE YOU BUILD US A 383 FOR THE ISLANDS,
Thank You Mr David. You are S True Gearhead. Go for it win win win. Air in Air Out
Subbed and liked… such a wealth of knowledge!!
Think this engine was in .....horse power on a budget..or another one..thank you sir for all your knowledge sharing information..glad you made a full recovery
Back in the 1990's when i was just starting to build cars I did tons of research, had all they dyno software as soon as it came out. I started building my own stuff in the garage and ran "huge" cams according to the old time guys. I ported my own stuff, did my own valve work (at a friend's shop) and built a 355 on a budget that put an 80 camaro in the 10's on very little nitrous and weel into the 11's on motor. I like high lift and low lsa, made great power and sounded excellent. When i had the motor ripped down to refresh i switched from solid to roller and let my engine shop frend and howards pick the cam. It sucked. I would up having them custom cut me a cam then it was even faster.
This is a very good video and that was really solid numbers for a 383 I also liked your cam spec info and where the piston should be in the block. Again thank you for the information. Rick 427
Smokey Yunick, Bill Jenkins, & David Vizard are my Heroes! My home built engines have stayed together & performed well over the years thanks to your great information. I can’t thank you enough! I’m looking for tips on getting more power out of a 350 Chevy 350 roller cam track 1 headed vintage road race engine with 48 IDA carbs on MacKay manifold. Should I bore them out to 51mm? I think I need more carb flow it’s weak above 7000
It’s a GM, of course it’s weak.
@@DoyleShadduckhahaha bro you are hilarious! those damn GM idiots right?
my wife left me
A friend of built a Yunick Stroker, had so much torque, sent the flex fan thru the hood, fender and radiator, during a good rev up. Twisted the water pump impeller right off. If he would have been under the hood giving her the ole Ugga Dugga, off with his head for sure.
It’s an awesome engine DV
Wonderful Video
Thanks David. Would love to get your input on building a MAXIMUM TORQUE SBC 400 in a 1997 K1500 w/5 speed and 3.73 axle for towing. Maximum compression on 93 octane pump gas w roller cam and stock vortec style heads. The only upgrade that has been made is the replacement of the factory fuel injectors. The reason for the maximum compression is that a CNG conversion kit will be installed and I want to maintain HEAT to compensate for the power loss from the conversion. Truck currently has 384,000 miles and a daily driver. I bought it used at 99,000. Engine does not smoke and never even had a valve job! Your thoughts!! RJ
I used a 4 hole spacer that i modified by gouging out the passenger side
Divider so it looked like an oval race track and it equalized the plenum so
Much that it sounded better on the dyno and with 4 jet sizes up it made 20 hp more, i know some was from fuel. This was on an air gap 406 sbc.
❤ a true master. Sorry for your loss 😢
Great Video David, I always learn from you. AG
high david thanks for another great one can you do a video on the 396 3 7/8 stroke build?
What is the vacuum on this motor? I would think it would be around 10 ? Love the video. I have to see it again.
Great vid David, I was interested to know in the exhaust part, you specify header pipe size but not design. At that power level, is it preferable to have "tri-Y" design or long-tube? Does either design just dictate where the peak torque is generated, or is that exclusive to primary length? I remember a comment you made about equal length headers not always being the best for power production, is that dependant on firing order?
I like what I see.. Great video(s).
Thanks David
I will be building a 383 engine
To your specifications.
Great video
I wish i had the change to get a job in this kind of shop after my mechanic school 🏫 but at 65 it’s to late 😊
I want to build a 421 for a street car that I can drive. With the maximum HP I can use.What do I have to change compared to the 383? Thanks again for your and Andy's great videos.
I love your videos and really appreciate the great information. I am looking to build a street friendly 383 sbc 450-500hp on 87 pump gas if possible. I am building myself a squarebody Chevy crew cab short bed and it will also be a 6 spd manual and have Holley EFI or Aces Killshot EFI. Any information would be great on what you would recommend. Thank you and please keep your videos going. I'll donate as I can soon after some things come through.
Great video, very impressed with David's knowlege.
i'm in the process of building a 383 and would like to duplicate this build, however it will be primarily a street car with occasional trips to the track.
I am concerned about lack of vacuum for power brakes with the tight LSA's qouted.
I am being very careful with my part selection and from what I have read, a tighter lSA means more HP but a rougher idle and less vacuum.
Can anyone shed light on this?
David- I am impressed by this video more so even than previous ones- because ALL your recommendations ECHO my past experiences to a "T"! ABSOLUTELY spot on with reducing the LSA from 112 to 107, lengthening rods from 5.7 to 6", and getting that lift higher and more symmetrical with 1.65 intake, 1.6 exhaust. I did almost exactly these things, also installing my 107 LSA on a 103 degree centerline ( my 440 Mopar was LOW on static compression ) ,and "down in the hole" at BARELY 8 TO 1, CLOSER to 7.9! With .518 lift boosted to .545 with 1.6 rockers, I achieved 572 horsepower in that smog motor ( 1972 440 @ 8 to 1!). This was at 6,315 rpm with Chinese 1.6 shafted rockers with bushed bearings and extra oiling holes I drilled in the shafts under each bushing ( the lousy oil holes where originally only under 1 of each of the 2 bushings in each rocker INSTEAD of BETWEEN them, and started to gall the shafts, which I caught just after break in already! (Flat tappet). This engine (amoung my others) is still killer after MANY trips from NY to NC, in a 1972 Chrysler New Yorker Brougham I literally got out of a collapsing barn in NC a few years ago, with about 80,000 miles in it, last run previously in the early 1990's. NO rust, MINT interior. I LOVE this car! I had a 1971 Challenger convertible, in which I installed a 440 six pack, and MANY other Mopar's. I'm currently building a 1973 400 SBC block going into a 1976 Chevy Monte Carlo. The Mopar's are my first and favorite for their superior geometry, in my opinion. Since the beginning of the 1970's, I was one of those guys the Chevy guys looked out for, because I knew what to do with getting more out of less. I BEAT the golden rule BACK THEN. YOU and I both now your MISSION IMPOSSIBLE is gonna wind up with a STOCK 800 cfm 4 barrel off a mid eighties cop car. I LOVE the Thermoquad! Made many a giant killer with them on 318 screamers. Best intake then was the (not stock) Edelbrock LD4B, BUT ANY 360 STOCK IRON INTAKE WILL get the job done after either porting 318 heads or using 360 heads on that 318. LOVE the 318 also! That was my first car- 1970 Dodge Challenger SE, little rear window, over head interior front to back console, and a wicked top end with that intake set up, headers, dual valve springs with dampers, and what we used to call a 3/4 race cam with solid lifters and the Mopar LA 273 engines adjustable iron rocker arms! You WILL EXCEED 1 horsepower per cube, I guarantee it! I'm starting to feel my age now, at almost 70, but the 2 loves of my life, my wife, Cathy, of 45 years the December 10th, and never ending fascination with the combustion engine, keep me going! Thank you for sharing your wisdom with all of us! Merry Christmas, and a happy, better new year!
I'm building a small journal 327 bored 30 over could, I use the 6 inch rods with that engine? Also what can would you recommend? Thank you!!! 😎😀
@@jamespepper2541 Optimum rod to stroke is around 1.8. SBC 350 is 1.64, SBC 327- 1.75. 327 stroke is almost 1/4 inch shorter- you DO NOT need a shorter rod- it would put your piston pin height quite short- about 1.2"- that compression height might cause piston rocking, especially not good in a street engine,band the 327 winds out great stock! In my opinion it is superior to the 350 in stock engine geometry. No need to waste money on rods and special pistons- but DAVE knows way better than my old layman street racer experience!
I already have 1962 stock rods, I just need to find me a good cam. I'm running flat top Pistons and it's bored 30 over ,😎
@@jamespepper2541 Again about a month ago, Dave did a video- 128 formula for correct cam for your requirements, with all variables and an individual's and preferences, and the fact I myself never built a SBC 327, I don't want to steer you wrong in cam selection, it's about the most critical part of how an engine's gonna run! Check with Dave!
Thats awsome iv been trying to find a similar build to what im doing so i could get a rough estimate of the power itll be making it ahould make 600 or so hp since ill be running 12.5:1 overdome pistons
I got a few older big blocks laying around 396 402 454 I got a couple c30 two wheel drive dually with 400 sbc I liked your 383 video....l would like to see what you like doing to older bbc any new info for 2023 on bbc thank u
I watched his video on tighter cam lobe separation- my buddy was going to use one that was 114 but he went with a 110 and made more power and torque
After watching your video I ordered one of your books
Does anybody have a parts list for this build? Or could we get one posted?
About that lsa.. i have 350 with Edel heads. Short headers. And i have bougth comp cams Cam and it had lsa 110.. should i try to get better? Flat tappet lift about 0.5 . 1.6 roller tip Rockers. Thanks for great videos.
great research
omg!!!! you are the man! thank you sooo much!
Awesome again.
Have you done any testing with E85? I’m considering a high compression street engine.
In Australia we have 98 Mobil and its oxygenated,, with alloy heads and modern combustion chambers we can run 11.5 to 1 and its not an issue.
Real Treat:)
Improve on this video?
No Sir - it’s a awesome video.

Thank you Sir, if I may ask what cam would you recommend for a 412 ci sbc 9.7 to 1 comp. being built for a tow/4x4 truck 1980 k20? The cam I was going to order is a 220@.050 intake and 231@.050 exhaust on a 110 lsa with
.469 in and .480 ex lift. Stock heads edelbrock performer intake and 750 carb. Also 1 5/8 headers with 2 1/2 inch exhaust. Would like your opinion if I'm on the right track. Thanks David
LCA on a 421 with big intake valves I a street street car? Thanks for the videos
Hi David,
Well I didnt know you had worked for Weber.
I did visit Jef How in West Kingsdown opposite Brands Hatch many times as he was Mr. Weber in decades gone by as his wife was the font of All weber jetting knowledge.
I wonder if you also knew Mike the pipe? In Essex master of building bannana bunch headers.
Of course there was David Newman camshafts in our area (Farnborough Kent) too. I guess its his son or grandson running the business now?
You keep making videos & I will keep clicking the likes.
Thank you.
I would like to know what you recommend for the LS engine specifically the 4.8L.
Hello Mr Vizard!
I realize that this is an older video but it's of subject matter where a question I have would apply.
I would like to start off by saying how I have enjoyed your work over all these years. I am 55 years old and have been reading your work all my life. I also have bought several sets of your mufflers over the years, as well!
Alright, I have a few questions about water jacket filling of a high performance street engine. The engine is a Ford 351 Windsor stroker to around 420 cubic inches. I say 'about 420' because I have not ordered the pistons until I see what the bores clean up at. I'm using a very old engine block for strength.
Back in the day, people used either lead or cement. I also remember how everyone who filled a block, filled it to a different levels.
I would appreciate your opinion as to what to use for a filler and how deep to fill the jacket for street use???
Any and all information is appreciated!
PS, I donate to St Jude around every year or so, and think that you are doing a fine thing to help the kids.
Take Care, John
What specs would you use for the full race version of this engine using a solid roller camshaft
Would dual 4" Ram Air and windage tray help?
On your exhaust system, what is your opinion on Dr Gas X crossover on an engine like this? Thanks in advance.
If I were wanting you or your people to recommend a cam for my 400 sbc, what is the price and what is the method, Mr. Vizard?
Were the cam specs listed what was used in this engine? i see the 107 lobe sep. My go to i use for a 383 or 406 solid roller is a comp 12-855-9 for a drag limited street use. 253-257 @50 645 645 on a 106 lobe sep. This works good with a afr 195 or 210. for a book cam this grind will make 0ver 600hp in a 11.1 383 and afr 210 and vic jr or air gap dual plane. Has a very fat torque curve.
3:44 I remember when 383's were first being built people were using 6" Olds rods.
Thanks David I was thinking on doing a 383 with a 671 do have combo setup?
LOVE this man!!!
Have you ever thought about adopting an older son? (I'm 63) 😂
Have you even compared magneto vs other distributor? Also have had dealings with Predator carburetors?
Sir Vizard..
I’ve been teaching people about gravity…
(The weight of air)
:)
Thanks Buddy :)
Hi David great video …. I thought at first you might have been working on a Mopar 383. What would I like to see you spec up? Base it on the 440 Mopar block (RB) and build a stroker (505/512 etc) with Trickflow heads (240/270) and spec for the street. At 500 BHP …. Don’t increase …. Go for milage and street manners (power not just at WOT). Thanks.
He or they will not reveal specs at all , just generalization.

Can I use an ported 800 cfm Q-Jet on this application or I'm just dreaming that it can make simular HP ?

.020 in the hole w .019 shim vs .005 out of the hole.
It matters do to head gasket bore diameter. I'm I correct here. The .oo5 out will net less over all chamber volume.
I'm I correct?
I do have an serious question. I wrote to Comp Cams, Lunati, and Howard Cams. All I got back was from Howard’s Cams. This my second 383. I am with almost with the same set before I saw this video today. I too have the Scat 9000, Scat 6.0 rods, Wiseco 11.15:1 with the AFR 64cc 1.6 Aluminum Roller Rocker. You talked about Howard’s Cam. They gave me 110275-12S. I really wanted an Lunati Retrofit Hydraulic Camshaft because the other 383 have an CompCam. What LUNATI would you recommend to me. Thank you.
I have built all kinds of motors, I really enjoy the uncommon. I ran 455 Buicks for years, along with Pontiac and Cadillac. Of course 50+ LS motors and can't even count the small blocks. I remember when running a low compression 455 I had a can cut on a 107 with quite a bit higher exhaust duration to make up for the crap exhaust port and it made far more power than anyone expected. Getting the cam and Carb right can make any combo
Uncommon? This has been around for decades
Thank you
How much lift was the cam? thanks.
Building a gen 2 lt1 396 would love to see how you'd build a 600+ hp lt1
I was wondering what the duration was at 50
Don't you have issues with brake vacuum with LsA of less than 110?
Thanks!
Have a 383 in my street 64 chevelle weighs 2950 I have found it runs strongest with inch and three quarter headers in two twelve inch long three inch diameter collectors in to three inch pypes x pipe exhaust
What about a spheroidal graphite iron l31 r , 4 bolt main block? Could that make 600 hp reliably?
thank you!
So David I was seeing some info stating a 106 vs 108 lsa almost changing MPG by as much as 5 MPG. Going with a 106 lsa and 106 lca. If that's the case almost no one should choose that combination on the street. That sounds like track/mud truck build to me.
Yes give us more information on a specific build with a dyno sheet at the end. Your 383 you showed at the end with 12.5 to 1 compression, are you saying that can be driven in pump gas on the street? If so is it because of the dynamic compression ratio, which I would assume would be affected greatly by LSA? I have a 383 in a 66 Caprice and I want to ring out every bit I can from it. Thanks again for sharing your knowledge :-)
Boss lots of modern day cars are 12 to 1 compression also engine masters did a test and it was fine on 91 pump gas
@@raymondguzman5083 engine masters engines typically run super high compression since they are still "new" and sealing out every bit of oil. Modern cars get away with high compression due to aluminum heads, coil plug ignition rather than a distributor, and direct fuel injection that ensures atomization. also their combustion chambers are superior designs, but a lot of modern aftermarket cylinder heads are right alongside.
look for hoow degreeing and how the Opening point and closing , in dynamic compression articles
@lennyperson6441 im talking about cars like modern day Mercedes and bmw they run 12:1 and other cars
@@raymondguzman5083 that isn't comparable because alot of them are direct injection or both direct and port injection and they have variable cam timing and coil on plug and they also have fancy knock sensors and the like all these things help them get away with more compression. My 2016 fiesta st is a 1.6 direct injected turbo motor that was pushing over 20 psi from a tiny turbo when stock and the engine still has 10:1 which is kind of high for a turbo motor running that kind of pressures. It's because it's direct injected with coil on plug, vct and also has knock sensors to pull timing if all else fails. An older engine build without alot of this tech it isn't ideal to run compression that high.
If you keep a stock blocked build within reasonable rpm ranges you won't have to worry that the engine will let go. Sure a sbc can rev to 8k but I would not push it past 6200.
Can you do a low buck 289 ford that sound be awesome
Thank you Daviid. ( for your channel) my name is Tom Hamner, I need help. I have an 09 dodge challenger about 80,000 6.1. I am 64 years young. And would like to build this right.
