BB Chevy 454 stroked to 525 cubes - super big torque! 

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 👍👍

Torque is what wins on the street...thank you sir and long live the big block chevy.

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.

I love the torque monster builds.. reasonable rpm and gobs of torque.

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.

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.

Always great hearing you talk about big block buildups and secrets, keep them coming!!! Thanks!

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.

Just bought your book on building a budget 454 I'm really looking forward to building my first motor based off of your advice thank you sir!

WOW, AWESOME BUILD... NICE CAM AND LCA.

Good build up Can never have to many bbc build up, please keep them coming

Thanks Dave what a way to start your weekend with a 750 hp BBC

I love all your big block chevy videos I love that you share the engine specs and tell us the combos

That's crazy power off pump gas wow

Reminds me of he early to mid 90's when people were putting big blocks in Chevy Chevetts!

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

That is just Wild!! and only 10.5 comp.!!! I wonder what a 13.5 motor with that combination would bring...

The best content on the net bar none. Now how about a 460 into a 514 with AFR heads.. Thanks for all you do..

Great video I love all the big block builds

Awesome build David!

Those BSFC values are lovely. 0.39 at 4000 RPM, 0.401 at 5083 RPM, 0.39 at 5900 RPM. It's efficient.

As long as you can feed them, and keep the friction losses under control, cubic inches are very hard to beat.

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.

thank you for sharing your years of knowledge

W O W ! ! ! That was a awesome dyno pull!! Thanks David! Truly brilliant build!!!

I like it. Good stuff Mr.Visard

That 105 lsa will narrow the rpm range of the engine.

Looks like an ideal jet boat engine

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.

What a torque and hp monster

Awesome content sir!

I just found your channel a while ago and subscribed during the first video

Great information as usual.

I believe the proper statement is "there's no replacement for displacement!" 😂

Absolutely Fantastic Engine 👏 😅 David . Gr8 Combination 👍 👌 😅

Thats a great combo for just about anything.

Very much liked the results

David is the best out there for making big HP

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.

Thank David love the video

Damn good Engine, well done.

Very impressive.

Great video

thats what i need in my 74 lwb C10. love it 87 octane.

awesome engine

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.

Goodness gracious, great balls of fire! Wow David. Special license plate "ENG-WIZARD". DK, Omaha.

Great vidja David 🤙🏼

Nice build

That thing is breathing really good.

Thanks. Take care.

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

O yea love to have that combo in my li’l jimmy blazer!

Good information.

Awesome video, i would love to see bbc low end pulling builds. Low end and mid range power is fun power.

HOLY crap .. that thing is AWESOME ill take 2

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

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. 🙏

Good job different Engine build on a Chevy , most of the time it's 496 or 540 and 525 with a stock block too.

I like that phrase ...The b.s. stops when the flag drops 👍. I wish my Pontiac 400 had that much hahahaha in my dreams

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?

Big Block the only way to Ride

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.

This is amazing, just what I was looking to drop into my 1980 k10, was only curious if anyone caught how much of a lift he used on the cam.

Badass motor.....

I would have liked to have seen the torque and hospower chart. I really like how your videos are to the point.

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

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???

Hot Dog that's impressive!

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 ...

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.

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?

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

Impressive

I bet I could build that engine for about what it cost to build my big block 427. ,thanks for the engine specs and video

I would love to see some air cooled VW's!

I have a 489 i want throw a 4.5 crank in now awesome power an torque

Engine was impressive, so is that dyno instalation.

“Prooven” 😄

What did it do with the 280 heads listed in the drop down?

Thanks David! Just changed my whole engine path lol. Curious as to what piston you used for this combination? Part number?

Hi, David. Would this engine work in a marine application where there is not possible to use a decent exhaust header. Would the cast marine exhaust and risers ruin it.

David have you done any tests on Ford Edsel heads? Bought a kit from Edelbrock aluminum heads and intake for a 428

If you had a motor like this with 12.3 and a lock out Dist.set at 35 can you run 100 octane in it?

DV what do you think about peanut ports for 5k and under for just torque ?

I want one of those

I wonder what cam would be best for a 376ci GEN3 hemi Hellcat motor. It's 9.5 to 1 with 2.14 intake valves. I'd like it to be aggressive street occasional strip. 6sp Challenger. I hear LCA and LSA. I know what they stand for but not sure when we are talking about each. Thanks

Awesome! I'm building a boat engine. Can you do a big bbc with Dart or World iron heads?

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 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!

If true. Awsome Bv

Damn. I wonder what Vizard/Walters could do with a 511-514 Mopar Wedge, with ported Trick Flow 270 heads? I'm a Mopar guy.

That idle proves its a smal cam

Nice just what i was looking for is IT posibel to her som part nr for strokerpart and cam and heads 😉

Hi David, do you think these heads 320 would work for a 496 combination?

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.

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

No substitute for ci they say. Yes there is Forced induction Bloodviking
