Hi David, Im at a loss at how many videos you have posted recently. You are an absolute powerhouse of information. You are helping many people think critically about their cylinder heads. Thanks for arming us with great information 👍👍
Thank you,Mr. Vizard for putting out such great content. Ive read many of your books in the last 30 years and learned more than i learned getting my automotive degree. Youre a real treasure,keep up the great work💪💪
I loved the story of this build! If you have any stories about working with a ford 460 I would sure enjoy that too. Keep up the great work, and God Bless.
Thanks for the details on the successful engine build. For dollars spent the Chevrolet Big Block V8 provides the best return in terms of horsepower and torque of most engines available to a performance enthusiast. This engine has been around since the early sixties and is still very desirable. The iron block is heavy but with aluminum heads, intake, water pump the weight comes down to a manageable level for many cars.
The last 2 engines that left my shop were done more your way than mine, and it showed, the sbc 427 pump gas Hy Roller made 577 torque and the BBC 540 pump gas flat mechanical cam made 753 torque, however my HP numbers aren't up to yours. 600 and 735 respectively. In fact the BB held 735 + or - 5 from 5900 to 6900 almost flat. while the SBC was more a conventional curve. I have learned a lot in the last year watching your videos and I thank you.
Before Money..there was a reason a Big Block Chevy was designed....and there are some out here that dont build over a 3,000 dollar engine due to economy and have to live.Most i Know here in east tn. have less than 10 grand in a build....talking g.m. muscle cars late 60,s to early 70,s.......why them yankees like to come down and pluke the ol car from us.....dont take much with a big block chevy to raise Hell on the street/track without breaking the bank....small block guy spend what it takes to build a Ford.
I've got a 57 Chevy truck that I'm building into a 4x4 been back and forth on either building up a 406 I have or a 454 I have. I was set to go 406 but watching this series makes me want to go big block. I can always put the 406 in one of my other trucks. Keep up the great content a big 👍 to you.
This is exactly the dream motor i have been looking for .... for my daily driver hot rod black s10... what a sleeper i shall build. 😁 a million thank yous David
Absolutely amazing to do this on 87 octane fuel. And amazing to stick that 4.5 inch crank in that block. I've considered a 4.375 in a gen5 block but I think it's the heads and cam combo that makes the big number possible.
Fantastic videos DV, thankyou. I have a 385eries Big Block Ford .030" over to which i want to run a Scat 502 stroker kit in. What this BBC has produced is what i desire to achive for mine, is it safe to assume that these specs basically carry over to the BBF? I was contemplating using a JKaase P-51 head but see it may not be as big. Any guidance would be appreciated. Cheers Ben
Thank you for your knowledge....dieing breed....gonna be hard for someone to fill your shoes and they are alot of gearheads out here in real world...Thank you for want share and do on here...Chris from East Tn.
A two plane dominator manifold... I like it. Wonder if production could potentially be in motion by August/September? Be fun to see some folks step up.
The secret it is the heads flow 400 cfm along with 500 plus cubes Makes the dominator carb force feed It enough to make all work If it had 13 to 1 compression it Would make 900 hp
David: Edelbrock did make a dual plane Dominator intake manifold for the BBC, labeled as the "C-454". Introduced in 1969. Not sure when it was discontinued. Would be nice to have a Dual Plane RPM Performer with that flange for BBC.
I randomly found a C-454 at a swap meet a couple weeks after watching this video and snagged it. It looks like the high rise chevy intake or Performer RPM with a dominator opening. I'm building a pump gas 509 (.030 over 502) right now and planned to use a RPM Air Gap and 950. But this video got me thinking about a Dominator so maybe I'll test the C-454 vs the Air Gap with a 950 when I get it together. My late father built and raced lots of Big Blocks and was also a David Vizard fan. So I hope to do this right and make them both proud.
@@etenterprises they really need to take the new technology that’s in the RPM air gap and put a dominator flange on the new Manifolds the older style manifold probably still not gonna make the power the rpm airgap will with 1000 CFM 4150 carburetor
Wow I am impressed. If I ever build a engine that certainly a great power plant. My brother has a 496 supper charged build in a Honda Integra. I will say the power of these big inch motors are a rush
David, I have a pair of 565cid (4.25" stroke x 4.600" bore) 9.80" deck engines that are ready for assembly, however they are for a MARINE application offshore hi-perf pleasure boat i mainly use on Lake Michigan. AFR 315cc cnc'd heads with some slight porting on the exhaust port for .700" lift. ...and I have purchased a pair of Edlebrock's dual-plane RPM Air-Gap Pt#7562 in the Rectangle Port design and that's what I am determined to use (don't want to use any single plane). I want a hydraulic roller cam to make peak power up to about 5800-6000rpm, DRY exhaust with 32" 1.7/8" primaries, 9.3:1 comp ratio, Holley 4150 950cfm Ultra XP carb (don't want a Dominator carb) I am a little concerned about reversion from too tight of a LSA on the cam profile, however I LOVE the low RPM idle characteristics of the Mike Jones Cam (450rpm at idle/neutral) ....I always thought the TIGHTER the LSA the more ROUGH and choppier the idle----no? I'm looking for TORQUE on these 565cid marine app engines....with/using the components/parts I have listed, what CAM specs/profile would you suggest and on what LSA???...and please keep in mind I want easy going smooth LOBES on the cams for long lasting durability and easy on the valve train. I am also using Crower Stainless Steel shaft mount roller rocker arms. I enjoy watching your videos and your tech info. Thank you, Sir....Mark Btw, I am NOT looking to make every drop of Horsepower at the top, rather I am looking for NECK SNAPPING TORQUE with these 565's and was planning on calling/using a Mike Jones cam as well. Any Suggestions???
There is a dual plane dominator intake. Cant remember who made it but my boss had one on his big block he had a 750 dominator on it. This was in the late 80s but holly made a 750cfm dominator
Really awesome video....Would love to see a video build on a stock bore 454...maybe gen 6 454??? Thanks so much for your valuable information...very much appreciated. 🙏
Only issue I would see is windage issues with oil. I had issues with stock 468 with oil aeration above 4K rpm. Curious what kind of oil pump and pan was used. Windage tray?
I can't afford aftermarket aluminum heads. I'm stuck with iron oval port closed chamber heads. Could you do a video porting iron oval port closed chamber heads? Thank you.
Hope all is well David just wondering if you can build a traditional Pontiac they are light years ahead these days !I think the record iir is over 4000 horsepower thank You!
I was watching the video Andy and John did last night and he mentioned welding up combustion chambers to gain compression on his 96 GT… DV could you do a video covering some of the tips and pointers of modifications to less than ideal combustion chambers and what to NOT do?
David have you ever tried SV1 carb on a BBC? I have one on my 468 race engine and it works better than any Dominator. I also, have a 1050 dominator #8896. My 468 puts out 800 hp. and 609lbs. torque.
I have a question about the cam. I am looking for a combination that makes good power and torque on pump gas for a boat that has two 454’s. This one caught my attention. My question is regarding the cam. I have been warned that some automotive cams can cause revision of water in boats. This is where the cam sequences allow the water cooled exhaust to draw water back to the exhaust valves. How would I know if this would be a problem with this cam? I am extremely interested in the combination as the power and torque would be amazing for the current 350hp 454’s the boat has now. Awesome video!
Now what cam would you like to see if you took this combo to 14 to1 compression.. And closer to 7800 rpm.. A taller single plane and a 2 in spacer as well.. I have the vortec 8.1 block which is a tall deck so I can use longer rods as well. Also with a bigger head like the afr 325
Dear Mr. Vizard I like very much all the tech you are sharing with us, I have always been a low bucks guy that likes to optimize my motors and now that you have clarify the cam specs situation I feel I can do better with my stock LS. so my question is have you written a book on what an LS engine likes? and also porting the 862 or 703 head? thanks again for all the tips and knowledge you are sharing with me.
David David David OMG Sir if I ever in my life ever rolled up to a stop light and heard a Big block barely running idling at 500RPM I would get out of my car and put a bullet thru the Carb.. I'm sorry david but a nicely built and appropriately cammed BB with a solid roller idling in at just under a Grand is all the music I need . Listening to a Mildly built BB with a set of older Stahl racing headers well that just Orgasmic ...
What kind of rod length were you able to het with the 4-1/2 inch crank and a short deck block?? Awsum build by the way. I’ve only ever pit 4.25 strokes in the stock blocks. Thanks for the video information Mr Vizard I appreciate them.
@@johnnyatkins9097 yeah but he said using a good stock 454 block. There is no such thing as a factory tall deck 454. 366 snd 427 were the only 2 factory tall decks
@@bcbloc02 yes where the 366 is a small bore block the 427 and 454 share the same 4.25 bore. So you can use them in any application you could use the 454 block in.
I’ve got a small block that is a aftermarket block from dart but it’s a 427 with twin 80/85s and we put it on the dyno up at tkm and it made 2.134 horsepower and we stopped that was at 33 pounds of boost and I’ve ran it up to 44 pounds at the track. It runs good but I’d love to build a bbc seems like you can make that kind of power and don’t have to gut it I mean they said mine had a bunch more left in it I just wanted it dependable but we all know race cars are not the only thing you can do is get a good program going with a good crew and try to keep it duck takes together.

WOW, AWESOME BUILD... NICE CAM AND LCA.
Good build up
Can never have to many bbc build up, please keep them coming
That is just Wild!! and only 10.5 comp.!!! I wonder what a 13.5 motor with that combination would bring...
I love the torque monster builds.. reasonable rpm and gobs of torque.
That's crazy power off pump gas wow
Absolutely amazing to do this on 87 octane fuel. And amazing to stick that 4.5 inch crank in that block. I've considered a 4.375 in a gen5 block but I think it's the heads and cam combo that makes the big number possible.
As long as you can feed them, and keep the friction losses under control, cubic inches are very hard to beat.
Thanks Dave what a way to start your weekend with a 750 hp BBC
Great video I love all the big block builds
Love the video. This is such great information. I would love to see a similar build and recommendations using a Pontiac 455 block as a starting point.
Boost

What a beastly engine. Fairly easy build. Of course the head porting and intake port matching are making a big difference, but it's time well spent.
Those BSFC values are lovely. 0.39 at 4000 RPM, 0.401 at 5083 RPM, 0.39 at 5900 RPM. It's efficient.
I like it. Good stuff Mr.Visard
Reminds me of he early to mid 90's when people were putting big blocks in Chevy Chevetts!
I don’t remember that but I do remember stuffing them vega’s.
@@iamOAKland not sure what rock you were under at the time, but the chevette V8 swaps were popular unfortunately 😆
