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.

This man is a genius, im so glad he chose to share his life's work all these years!

Thank you taking the time to share your knowledge.

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.

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 KZfaq, 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. 🙏🏾👏🏾👍🏾

Thanks!

Completely and totally awesome.

Bloody hell, you’ve just solved every issue for every 383 builder in the world, with dyno proven facts. Thanks again DV.

David Vizard is amazing take every word he says to the bank.

Hi David, I've been following you for most of my life have some of your old books from the 80s I believe, and have been flowing Heads since the late '70s, mostly Motorcycle heads. One of the last for-profit heads I did was for a race team I sponsored for fun at a semi-pro turning Pro level. When working on the stock Yamaha Head and looking at the factories machine cut seats, for titanium Valves I noticed how recessed into the head they were and how the cut effectively placed a tight 90deg to the flat of the valve seat insert wall all around the valve at low lift. Seeing how they had long Duration cams in them with quietening ramps, I modified them, not liking the sharp edge that was close to the valves. Flow improved on my flow Bench, but one of my riders had a big mouth and told other shops of what I had done, to essentially second guess everything I did. He didn't mind all the wins and record laps He set, but had trust issues so we called it quits. However, I would appreciate your opinion on this type of cut seat as I feel what I did was correct, and why would a company Like Yamaha turn out Heads like this is it just manufacturing costs, etc, or am I missing something?

Thanks for sharing. Your name is mentioned all over the car world of KZfaq.

Absolutely no doubt about the bloke bloody ledgend

Have an 010 block handy, going to basically follow this build, 500+hp is my goal. Be a fun daily driver, probably high 11 sec car or so.

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.

Thank you David, I've bought your books but hearing you speak about this seems to be more rewarding

Thanks, David. I loved these 2 videos on selecting to parts to make a great combination. Please do more!

Thank you Sir!

You are the MAN!!!! Ziggy. Sigifredo Garcia 3

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!

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.

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.

outstanding!

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.

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.

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.

good lesson

Thank you for sharing both your build and dyno results. The tips you provide us with are very valuable. Again, Thank you!

You make a great engine

nice info David learned alot thanks! p.s. sorry about the loss of your partner, I pray that his family is ok!!

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.

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 DV your insight in very valuable indeed.

Sorry for your loss David, thank you for spreading your wisdom and helping those not as experienced as you.

I love these recipe engine specs, thank you for sharing your knowledge with all of us! Please keep them coming as you see fit.

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!!

Thanks for the info Mr. Vizard. It’s always fun doing budget builds and see what you can get.

Thank you for shareing your knowlege and pictures, lots of priceless information here, I hope you keep it up.

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!

Absolutely great, thank you.

Thank you for this. Well Done.

Loving this video. Great info. Thankyou

Thank you for taking the time to teach us from a lifetime of dedication and hard work!

David v. Your formulas are the foundation of every engine I build .ty sir!

I sure would love to see a Vizard Cleveland build.

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!

Amazing, I love it. Thank you so much for honest, reliable information!

What an amazing video. I am just getting started and he cleaned up quite allot of things

I cant find any history but he sounds like he's from Yeovil. These videos are like ASMR to me.

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. 🏁🙌👌

Thanks for the great video. Looking forward to some big block builds.

Verry good information, thank you.

Great content! Thanks for sharing!

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!

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!!

thank you for all your yrs and effort, don't go away. we are running out of people that know

Very informative, it’s great to see the insight that goes Into the part selection. Nice job!

Another valuable video.

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!

Man, such great stuff, Thank You

Thank you this is wonderful.

Should I run a pcv valve on my 383 build?

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 .

Tack!

Mr. Vizard, thank you for sharing your expert knowledge. It is priceless.

Great video. Always keen to learn. And your explanation and knowledge was top notch.. thanks.look forward to seeing more of your builds...

Excellent job what a joy to listen to you and gain knowledge.

Sorry for your loss

Thank You! I always learn so much from you.

David you are the man

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.

Learned the right way to rebuild a 350 from this guy. It helped me a lot on a Pontiac engine plan

Awesome

thank you again for your every thing

Realy liked the style of this video - good information concisely presented.

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 KZfaq as well.

Well done. Thanks again.

I thank u r a genius n every body is playing soft ball HHR rrr

Loved the video lots of knowledge thank you sir

You are doing great, I always learn something from every video.

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!

Thank you for the informative video I'm going to take your advice and get 1.6 rockers for my 383

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!!!

That piston looks very interesting. Every part can be improved on, every little bit helps.

Priceless

Great video

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😎

great info

Very inspiring

I enjoyed it.

Use a Roger helgenson anti reverson valve job to get rid of some of that torq dip

Mr. Vizard does it application apply to a L31 block as well?

Mr Vizard, i have bought every book you have written except the minicooper ones. Id like to know if you will have any new publications coming?

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 KZfaq combined. Thank you for sharing all your years of knowledge.

The most appropriate suspense sound at the beginning of camshaft selection made me 😂; cool stuff !!!

I'm a bit confused with the cam terminology used here. The screen shows LSA and DV calls it lobe centerline angle. But the lobe centerline is not typically the same as the LSA. So, is a cam with a 108 LSA being recommended, or a cam with a lobe centerline at 108? What about a cam with 112 LSA and 4 degrees of advance, putting the lobe centerline at 108?

Only suggestion, and it's because I'm lazy, but having a list of all the parts from the block down to the gaskets used would be beneficial. Is a higher alloy Dart block better than one from Chevrolet Performance, for instance. When and if my health improves, I'd like to build a nice street motor to put in a C-1 or C-3 Corvette. Oh well, thank you for the most informative videos.
