- In this, Part 2 of episode 50, DV tell how the low buck 383 he built was within a tenth of the record holding and reigning champs hi-buck 420 incher. All this was done with a car and tow truck that cost about 2/3 of the cost of said champs engine. It has been said that the BS stops when the flag drops. See how fast DV's 383 went when the light went green. The speed of this low buck build is well demonstrated in part 1 and the details of this and similar builds in this, part2.

This man is a genius, im so glad he chose to share his life's work all these years!
Yup! I fully agree with you bud!! He’s a awesome font of hi tech information on engine building

Mr. Vizard has forgot more than most of us will ever know. Several years back I sought out his knowledge for a ultra competitive 565 N/A Big Block Chevrolet and he gave me so much fantastic advice.
The 565 I built in my home shop based on alot of his insight is still in my Race Car and has seen hundreds of passes with regular maintenance and care, using good reliable, rebuild able money saving parts of fantastic Quality I have opened it and checked everything 3 seperate times and all we have done was replace one weak valve spring, and all gaskets every time we tore it down for inspection. I religiously cut my oil filters and inspect them under a microscope looking for any metallic particles that can foretell a problem and much to my relief I've yet to find anything other than normal wear and tear....This was my first attempt at a true blue printed engine where everything had to fall within designated tolerances and weights and while it did get frustrating from time to time during the assembly process....you would be hard pressed to find a person who would disagree with the outcome.
I've done a lot of winning with this Engine and plan this winter to pull it clear down and methodically replace all the Bearings, Rings and anything in the valve train that looks like it's showing wear and look forward to many more happy stress free weekends at the Drag Strip. Thank You Again Mr.Vizard you are a treasure to be sure.
Bloody hell, you’ve just solved every issue for every 383 builder in the world, with dyno proven facts. Thanks again DV.
well, I didn't hear anything about a .860 base circle cam... Kinda big deal.... but sure enough, DV is heaven sent no BS logical info.... rare these days...
I was just out of Middle school in '98 when I discovered one of your books in my automotive instructor desk. When I asked him about the book he mentioned briefly that you were one of the best engine builders he had read about. And just like that I kept searching until I came across Cartech books and I've been reading your books ever since. 40years old today. When I found your content on CZcams, I felt like I found and unknown secret again. Thank you so much for sharing your wisdom all these years. You have a long time fan here in Miami FL. 🙏🏾👏🏾👍🏾
I like this format where you describe the actual parts used so someone with less knowledge could reproduce it. Thank you David, and sorry for your loss.
What a great man to freely give a lifetime of winning race engine experience to all that follow him. Give a thumbs up and a comment.
Thanks David!!!
I gotta tell ya, I'm sad that it took me until just this week to finally stumble onto this channel. Such a wealth of knowledge here - it's unbelievable.
I’m sorry to hear about your partner’s passing. But I’m really stoked that your knowledge is being preserved in this way. I’ve read some of your books many years ago and was excited to stumble upon your channel.
Give it up??? That’s the only wrong thing you’ve said David!! You sir are a highly valuable source of information in engine building. Your legacy and history is in a high degree of excellence.
Honestly the only person I can compare you to for this degree of self taught knowledge is Gail Banks! That’s in my opinion! Only you are more in-depth and open in teaching others your vast accrued knowledge.
I would imagine that I will be speaking for the majority of your subscribers when I say this! God bless you David!
Thank you David, I've bought your books but hearing you speak about this seems to be more rewarding
Definitely continue doing this David. Theory can be fascinating, but critiquing real-world applications helps put things into perspective. Plus it's usually offered with a series of anecdotes, which are always welcome. 🙂
Thanks! Love this series. Please do more!
thanks for the generous donation sir.
DV
I've been subscribed for a while D.V. I'm so sorry at the loss of Marvin...Thanks so much for passing on the vast Knowledge on here. The format of the last couple videos is spot on Bud, thanks again, and God bless!
Thank you DV for sharing your life work- I own most of your books and have watched all your videos and I am amazed.
I truly believe your a genius and a great man for sharing and teaching others.
I’m a mechanic and it’s changed the way I look at engines.
My condolences on the loss of your partner, keep up the good work, i love your work
David: My condolences to you and your partner's family for their loss. You have had a great deal of challenges to face these past years. I should also send my deepest regards for your work, and the admiration I have for you. God Bless!
Thanks, David. I loved these 2 videos on selecting to parts to make a great combination. Please do more!
Thank you for sharing both your build and dyno results. The tips you provide us with are very valuable. Again, Thank you!
Thank you taking the time to share your knowledge.
I love these recipe engine specs, thank you for sharing your knowledge with all of us! Please keep them coming as you see fit.
Very informative, it’s great to see the insight that goes Into the part selection. Nice job!
Thanks for the great video. Looking forward to some big block builds.
Thanks DV your insight in very valuable indeed.
You are doing great, I always learn something from every video.
Amazing, I love it. Thank you so much for honest, reliable information!
Thank you for shareing your knowlege and pictures, lots of priceless information here, I hope you keep it up.
Great video. Always keen to learn. And your explanation and knowledge was top notch.. thanks.look forward to seeing more of your builds...
David, I am grateful for your knowledge and you sharing it with all of us. You are an inspiration to us enthusiasts and I'm sure the professionals! Thanks again Michael Voigt.
I can't see how you could improve anything. The information you give; well there are no words to describe it. You are awesome. Keep the information coming. Thank you.
David v. Your formulas are the foundation of every engine I build .ty sir!
Realy liked the style of this video - good information concisely presented.
Excellent job what a joy to listen to you and gain knowledge.
Sorry for your loss David, thank you for spreading your wisdom and helping those not as experienced as you.
Thanks for the info Mr. Vizard. It’s always fun doing budget builds and see what you can get.
I have a freshly completed .040 over 350 4 bolt main on the stand, but after watching DV's video's I think I will take it apart again and REALLY go through it!!
What an amazing video. I am just getting started and he cleaned up quite allot of things
Thank you for taking the time to teach us from a lifetime of dedication and hard work!
I sure would love to see a Vizard Cleveland build.
I’ve got a Cleveland going into my 86 mustang next. This engine went a best of 6.08 in the 1/8th on a 150 shot with factory closed chamber heads, mechanical roller cam .711 int .714 exhaust 262-272@ 0.050 300-306 degrees advertised on a 108 intake centerline. Chris Parker funnel web intake. Forged flat top pistons, Scat I-beam rods, factory crankshaft. I was running 4:30 gears and 31 degrees of timing on nitrous. This was in my 81 Capri with the stock K-member. I know I could’ve gotten into the 5’s in the 1/8 with 4:56 or 4:88’s. My mustang is all Team-Z suspension, coil overs, and weights about 300 lbs lighter than my Capri. I’m building a 6” long rod Cleveland right with CHI 3-V cylinder heads-same camshaft. Yeah Cleveland’s are the baddest of any small block platform.
@@StainlessTIG2 Awesome. CHI heads are on many 550 to 1000hp n/a builds.
As always awesome content. So sorry about your friends passing. Look forward to all of your information, been reading your books since I was a teenager that was a very long time ago!
Mr. Vizard, thank you for sharing your expert knowledge. It is priceless.
Loving this video. Great info. Thankyou
Thank you so much for the generosity of sharing your time and knowledge. Highly enriching. Felt like I just ran into an old friend and rediscovered all of the finer things of life. 🏁🙌👌
thank you for all your yrs and effort, don't go away. we are running out of people that know
Thank you for this. Well Done.
David this video is probably my favorite video amongst all your videos. It gives a better overall feel for a street based engine, and system based approach to component selection. Thanks for sharing the knowledge!
Absolutely great, thank you.
Very informative and very entertaining. We all appreciate your content.
This channel is dead for now, find his other channel here: www.youtube.com/@DavidVizard
I look forward to everyone of your video's,
please don't stop. I get more out of this and every one of your books then all of CZcams combined. Thank you for sharing all your years of knowledge.
I've been working on SBC's since I was 16. I thought I knew quite a bit about them. HA! Watching your videos are like going from elementary school to UNIVERSITY of Small Block Chevys. Thank you so much for your extreme technical advice and knowledge. It all makes much more sense now. I learn "something" more from every single video of yours. Good job Mr. Vizard!
That piston looks very interesting. Every part can be improved on, every little bit helps.
The most appropriate suspense sound at the beginning of camshaft selection made me 😂; cool stuff !!!
Thank you so much for sharing your hard earned wisdom with the rest of us ! You don't guess, you find out the facts. In academic terms, you are a "professor", with a library of research publications. Reading your work takes so much guesswork out of engine building. And I have learned some things the hard way; so much easier to build off your experience ! Your detailed analysis is stunning.
A plus in every aspect, knowledge, communication, great musical score, video quality, subject matter, pace, graphics, i 've not seen any video on this subject matter even come close...THANK YOU ! And I am sorry you lost a friend and cohort, may you grieve not long and may his memory stay alive in you for all time!!
One of the best videos on CZcams !!!
Learned the right way to rebuild a 350 from this guy. It helped me a lot on a Pontiac engine plan
Another valuable video.
Sir thank you so much for sharing your knowledge . I can't turn off your videos ,found you on uncle Tony's garage but had to follow you home ,amazing information . I will be buying your books on amazon . Take care and God bless.
Thanks for all you’ve done for us over the years. I have all your excellent books & have read your magazine articles over many many years. Met you at PRI West when it was at San Jose so many years ago.
David, thanks for the St Judes donation and BTW that's a super first name you have. And that might I add, is a totally un-biased opinion - just ask my mom if you have any doubts on this point!!!!!!
thank you David , sorry for your loss and deepest condolences. I'm 52 now and your books have helped me so much especially with the car I've driven everywhere most of my life . Everything in those books works on a 318 Mopar. like they say ,they're just air pumps . Thanks again mate and take care .
Thank You! I always learn so much from you.
I can sit and enjoy listening to an expert like Mr vizard all day
D V is Hammering out the videos these days thank you
Mr David Vizard, I’ve purchased 5 of your books recently and I’ve only begun to read the first and I’ve learned so much and I’ve been assembling “hot rod” engines for 2 years now steadily and I learned so many things in the first two chapters that I was unaware of. You are a brilliant man. Your legacy will be great. I’m so glad I found you on CZcams as well.
David, I've really enjoyed your videos and I'm so grateful you have shared your knowledge with the world!
Superman's got nothing on David😎
Verry good information, thank you.
So sorry to hear of your loss Sir my condolences to you and your family.😎🙏
Amen!!! David Thank YOU and Please DON'T stop God Bless!!
Man, such great stuff, Thank You
Great content!
Thanks for sharing!
Thank you for the informative video I'm going to take your advice and get 1.6 rockers for my 383
David you are the man
Yes I will Like, yes I subscribed, this video and yohe others, I see, are GOLD. THANK YOU.
Not sure you will see this but let me write anyway.. I bought me a 79 camaro for a steal of a deal. Its got a build 383 sbc 4 bolt from a few years ago. I am waiting for the build sheet to arrive from the previous owner. BUT. after watching your video I smiled as many parts that I see or know of on the engine line up very closely to your build in the video - namely the dart heads AND the same rockers upgrade, 750 quick fuel carb.
Thank you for sharing your knowledge.
Loved the video lots of knowledge thank you sir
Well here I am. 72 years old building a t bucket roadster.
Still making your advice my
number 1 priority. Thank you
and God Bless.
Priceless information here. Sorry for your loss.
Thank you this is wonderful.
Cool to hear you mention Jones Racing Cams. Mike is a friend of mine from our Los Alamitos High School days.
thank you again for your every thing
David you are so right that the cam is critical with LSA !!!
Skill testing question here Bob explaining why David is right : Why do cam manufacturers grind in wider than recommended LSA angles ?
@@luckyPiston easy they don’t want customers calling in saying their valves hit the pistons. Wider Lsa makes it much less likely to have clearance problems. People will never complain about the 20hp they never had or knew they could get but they will for sure complain when the cam they bought won’t fit.
@@bcbloc02 That's a pretty good one, i'm thinkin a cam with wider LSA is easier to tune and for people who don't really get carburetors and how to set them up (like power v/v changes) they can basically take one out of the box stick it on the engine and it will run, a wider LSA is a little more tolerant at idling against a tight torque convertor too.
Very great full for your hard personal persistent experience work of ART.
VERY SORRY TO HERE YOUR EXHAUST SYSTEM PATENT ARE NOT SOLD ON THE MARKET.
David, I have just built a 383 exactly as close as I can get to your specs. It is a family project between my dad, brother and myself we are super excited to start this up in the next few weeks. Here is a rundown of the build.
Quench set at 0.034LH/0.036"RH with flat top two valve relief pistons, 6" rods, Canfield 195cc/65cc chamber heads ported per your specs, Lunati solid roller DV293-06 camshaft, Weiand stealth intake ported to match the heads, Holley sniper EFI. Really hoping to make some good horsepower numbers with this build and would love to send you a video of it if we get it to the dragstrip this year.
Thank you so much for the years of information your an inspiration
I got to say. You are awesome. Love your videos
🤣😂 "520 hp is kid stuff " that cracked me up. This guy is awesome. That's right David no sense in playing around with that weak stuff 😁👍🏼
Please keep these videos coming.
No guess work here...we are lucky to have this guy!
Me and my dad watch all your stuff. Every book you've written on SBC we have. He follows you cause every thing you say is proven. I follow you cause I've seen his engines on the street and strip out perform big money. He builds to your every word. I hate when people hate on you for calling out cam companies, but the company has to be safe I get that.
Built a badass factory roller cam 383 A few years ago for a buddy. Turns out they also threw a 150 hp shot of NOS on it! Apparently they never had any problems with it but cam lift was around .490" with the factory self aligning rockers! 😆
You can't go much over that lift with an OEM style roller cam because the lifters hit the link bars. I've heard of guys milling the lifters so they can get extra lift out of them
Thanks for the information, it’s very helpful….
I cannot comment beyond saying that I am just a student here and unlike most lectures I have attended ...Sleep ,distraction and boredom were not in this personal classroom ...I have an blueprint sbc 383,(circa 2010) with an XR 276 cam ,Machine shop heads heads @ 2.02 intake and i cannot speak of breathing volumes ,but I will say that with my street demon 1904 /with 1/4 "spacer,(for too rich problem),..2k stall she runs great ...But you cannot get by with what you THINK you know ,so your series is VERY important to me,so Thanks....
one of the funniest cars i ever had was a 66 Chevelle with a 383 my dad and i built. i never dyno it. but it sure was fun af to drive, especially when i spent the money to get it to hook.
Absolutely no doubt about the bloke bloody ledgend
Well done. Thanks again.
Most informative, practical guide to parts selection and what their capable of! Love it, keep up the great work!
Priceless
I enjoyed it.
You definitely have spent time with building engines. The results are well documented. I have experimented with a 351C with 4V heads. I found that the engine produced a ton of HP but it needed a high flow exhaust, porting, high compression with a crane roller racing cam w/rockers and springs. The ignition mallory with accel coil. Carb Holley 1150cfm.
It would break engine mounts, transmissions and differentials.
Biggest draw back was the oil pan.
Front mounted oil pickup tube would stave for oil as acceleration increased.
6.0 rod pulls the piston away from TDC at a slower speed and that extends the torque curve to a bit higher RPM and that makes power. The cam/ports only know piston speed and a longer rod makes it seem like the engine is revving slower. This will also often raise the torque peak RPM as well but that is the tradeoff.
Aye, the longer rod results in a greater rod-ratio, and hence lesser secondary imbalance. (which is the term used for how the piston travels faster at TDC and slower at BDC, resulting in forces on the crank that oscillate twice as fast as the engine)
Joe Sherman did a test, found short rod SBC 406 had more power below 6200 RPMs. long rod more above 6200 RPMs...
Great video
Great video. I was definitely taken in rod/piston/cam info specific for my next (another) Holden 355" build.
Keep it coming DV, and yes, definitely telling all my friends to subscribe.
what times you expecting out of that white lightning this time around? you're still on bananas at the moment hey ? or did you end up going come? been awhile since I'd read one of your threads.
@@hayden6056 lol, hey mate. I'll have to work out who you are on JC. Yeah come TTB manifold. Been slowly refining the tune lately.
If I can get it into the 12's in full street trim with all the usual luxuries (A/C, cruise, p/steer) intact I'll be quite happy for a while.
@@Deuce1550 not on there anymore man got sick of the shit fighting. I was bad for it myself kept biting at a certain someone who'd underestimate the cost of everything and fill people's heads with fairy tales.
I was like why am I arguing on the internet when I can be restoring cars or building motors. Less time on socials , more time in the shed.
Have quite a few projects but one that'll help job the memory... Is a vr factory 215i senator with a Harrop single plane 😉
@@hayden6056 Mr Collins. Harrop.senator
Found you.
Subscribe to my you tube. I've spent the last 2 years building my truck up from a bare chassis. I'll try add car stuff when I go racing later in the year.
If replacing crank anyway, might as well go 383 or 400...
Keep doing what you're doing helps us all Because you are the man thank you!!!!! Sigifredo Garcia 3 Ziggy
