- In this, episode 122, DV & Terry Walters go with a less than orthodox route to achieve a 1000 HP plus, 87 octane, street drivable BB Chevy.
Not only do they clear the torque and HP goals set but also manage it on a way, way lower cost than GM's almost unavailable 1000 hp 632.
If you are interested, this, the prototype is now available in 'as new' condition for just $19,500 which is way below the usual $32,000 or so that most BB's of this calibre go for.
Amazing information that no one else even knows or talks about. 87 octane and 1060 hp with 930 ft/lbs or torque naturally aspirated is unbelievable! Good job David!
I’m not in a fuel crisis, I’m in a money crisis to pay for the fuel😂😂😂
Just a heads-up: I worked in anti-counterfeiting, and much of the work was done in the petroleum industry. Testing pump fuel (particularly here in TX) consistently proved that E-85 was typically anything from E-0 to E-10 or -15, and almost never E-85. This proved to be a problem that originated at the blending stations and the distributors and retailers didn’t even know of the deviation. Moral of the story: trust, but verify. If running a vehicle requires E-85, my strong suggestion is to purchase it in containers and test it without blindly putting it into the vehicle. This way, you can make adjustments, or get new, without trashing your engine due to detonation.
How would one test it? Specific gravity perhaps?
@@terrygreene5953
The simple method works well. You add a prescribed amount of water and it will pull the ethanol out of the fuel. You can then measure the volume of water/ethanol and compare that to the remaining fuel.
That's very good to know. I'm currently building a SBC that I was planning on running on E85 because it's high octane, cheap, and readily available. If counterfeit E85 is that common, perhaps I should rethink my strategy. Thank you!
@@terrygreene5953
Trust, but verify. I know people who run E-85, but they pump it into containers and test it. So, if (when) you get a bad batch, now what do you do with it?
I like to set my builds up so that the dynamic compression allows the use of 93 octane for street use. Race cars, I run leaded race fuel. My son has a naturally-aspirated Fury III that makes 730 HP. It runs 14/1 and we use leaded 100 octane.
Your last name might as well be Wizard. This is such great info
Awesome info sir! I would love to see you prove the 396 bbc engines pump gas potential. Thank you
RIP to the young lady Jacque Vizard
Thank You, For your information and everything you have put on your website for people to learn, for free!!!!!!!
Secret is port velocity & the right cam timing with perfect machine work
Connecting dots as always Mr. Vizard. You often make me think "Of course! Why didn't I think of that?"
I've been asking these well known automotive tv build shows to build the highest HP engine using 87 octane... And of course it fell on either deaf ears or ppl in the comments saying it's a waste of time. I would like to see the highest HP, turbo charged engine build using 87 octane.
I really like all the information about water injection!!!!!!
Thanks Mr.David love your opening statement about understanding the beast, our old school guy who's known for having the fastest mud trucks around told me when i wanted to learn how to build engines, that first i needed to study the engine and once you fully understand how everything works that you could do whatever you want with them
DV my friend…
Here’s some wonderful machinist out in Colorado.
I shared your 632cid with these guys.
Putting the word out about THE BEAST:)
The Beast for Sale :)
Great price for that 632....
I remember Winston Cup Series in the late 80's through the 90's restrictor plate engines running around 17.3 to 1 cr at Daytona and Talladega.
This is your best video yet. I would love to hear more on intake valve sizing per unit of displacement. Is the 2.02 SBC a good reference point for all engines? Does the same ratio apply to 4 valve per cylinder engines?
Eccelent video as allways.
SAAB started to use water injection on their turbo engines in the 70:ies. Well proven technology, knock sensors and computor running ignition and fuel injection deleted it in production units, but still valid for boosting performance.
Thank you David for sharing your experience and knowledge.
Head choice will be interesting
He already said which one
Mr Visgard
Thank you for sharing your Wisdom
❤🙏
It’s Precious to me
I think the expansion ratio of water to steam is 770:1 sompum like that , These guys are building a hybrid ! having yur detonation control also provide expansion just makes perfect sense
Thanks David. I'm going to have to watch this one again! I was listening while working on my 0 backpressure exhaust system. Gotta be done tonight
Thanks, David, for another great video. Your water injection testing has me going now in the same direction. So far on my 2.0L 4-cylinder 4G63. I've tested this engine on 91 pump octane running 75% water to fuel with great results. This was at 38psi worth of boost.
King David - this video is awesome
When this 632 revs on the Dyno
It almost sounds like an electric motor.
It’s insane - it’s a Beast as you say.
INSANELY POWERFUL
It really does taking selecting the perfect cam, and ignition system, because high compression with bad combustion = quick devastation.
Thanks VERY much, DV and Andy!
Thank you for saying using a higher ethanol gas results in significantly worse mileage. Its true, no matter what ratio you run, there is less energy available per unit of volume. Sometimes it feels like nobody believes me when I say this stuff.
And the straight alcohol craze these days😅
That's been proven in E85 vehicles years ago
@@Guns_N_Gears I don’t dispute that, but all the fuel management shit you have to do on efi cars to make them run it. Sure it’s cheap fuel, and in a lot of areas you can’t find straight e85, and they use a hell of a lot more of it.
@@TheMajictech Thank you, my sediments exactly!
Watched this one twice David, this is the information I thrive on..I have been working on a 750 stroked sidevalve harley with a different valve set up, no combustion chamber above the valve, from 5 to 1 to about 11 to 1. Thanks for the cam information it will help big time. D White.
Been looking forward to this one, I’ll admit it
Welp… looks like I’m off to watch episode 99 😂. Great video DV thanks for sharing your research and experiences.
Methonal and water seems to be the best mixture since methanol adds octane as well .added 3 psi water methanol and made 80 wheel hp 571hp 520tq 10 psi 99z28
Nice.. That’s impressive, Good work guys! What a value,What a deal.👍🏻
David obviously u have worked out this combination 2 the enth degree 😅 Just wondering would this combination that u have used here still work with a Tunnel Ram on Top ??? Thx u so much 4 sharing Ur wisdom & knowledge 😅
Blessings 2U Robert Australia 🇦🇺 🙏
Even though I won’t be building one; the information is very useful and interesting.
So this engine made 1020 hp on 105 octane fuel, and has never actually made 1060 hp or been run on 87 octane fuel - correct? Not saying that it couldn't or that it won't, but just trying to clarify here.
Super thank!!! And super informative. Thank you David. I always enjoy your no bs content
Excellent presentation, as I've come to expect from the Vizard world of knowledge!
(Also, it seems David lost his granddaughter(?) at 19 years of age - never forget that grief is the price of LOVE...)
His Daughter..Engine builder and race car driver herself! RIP❤
I would love to see it run with a 240 duration cam. I feel like that big duration to keep it from choking up top is really hurting the bottom. With that compression I would expect at least a ft-lb/cube from off idle.
Hey Mr David Vizard . Another Gr8 engine . Don't know how u pulled magnificent HP from this 632 cu inch & on 87 octane.
Chevy Crate Engine 1004 hp & 874 tq . Would ❤ 2 see 👀 the spread sheet of both engines figures.
Sounds like urs might be stronger across the board 💪 everywhere 😅 well done
Super Thanks 😊
Thank you for the great video David, I'm just wondering what do you think about a 390 block with 428 heads on it oversized intake valves and it had a 750 double pumper on it and I had to idol off a street to get it rolling and then I could give it more gas otherwise I was sitting there just spinning the tires but it was fun again great video appreciate your knowledge
What if: tunnel ram with port injection - each cylinder tuned for optimum A/F ratios and ignition timing?
another reason diesels get better economy is no intake manifold vacuum due to no throttle restriction at part throttle cruising
I've also hit the like button as always on your great viedeo. Thanks for sharing your wisdom.
What’s the best vehicle for the 632 Beast?
Maybe a step side 70’s Chevy truck:)
Lots of hood room:)
Like Andy’s Casper
Nicely tubbed 70’s step side:)
Have you looked at the intake manifold pressure during the dyno run? I think with the cam event timing in conjuction with the high CR, that the engine will experience higher than normal pressure, allowing better breathing - (kinda internally supercharging)
Idk i'm thinkin yur confusing pressure with velocity , Bernoulli's principle says if you hav low pressure and high velocity u will have volume flow , which is what we want , now if we want to find your supercharging pressure i would look at the backside of the valve rather than the intake manifold and i think pressure there is gonna be based on pulse waves traveling back and forth in the runner , i would be asking DV & TW what consideration they gave to intake runner dimensions in terms of ram effect and cam timing. Thats a tall intake more like a tunnel ram.
@@luckyPiston But is there any flow reversal?
Great info Dave
Do you have a build sheet for that engine build?
Great video..👍
What about a marine deal. For a v-drive v bottom with gears. Got parts for a 604 or a 572 tall deck. Race rite as cast 345.
would love 2 c a video on improving or building a clone to the L88 427 bbc...!..i know what most would say...out dated,dont wast your time....personal prefrence...!...thanks David...well explaned...& fact filled video...!..stay healthy..!
It’s on sale???
$19,500 ???
That’s a deal - excellent deal …
It would be good just to have as a display in the office …
Awesome as usual.
I sure wish I had a exta 19.500 that's a hell of a deal for 1000+ hp engine.
Id buy it if it was a few months in the future.
Muy buena explicación todo un profecional que equipo de inyeccion de agua utizo en el proyección un saludo desde Cuba
Thanks!👍
2.7 valve? where can you find that massive valve? I am running a 2.35 in my car 632 at 13.2
Great vidja 🤙🏼
Just when I think he has shown us all that's wrong with engine building. This comes up. Near equal torque and HP on pump gas. 1000hp on pump gas at 850rom idle. Wow
Another couple of Questions 4U David .. a Holley Race BBC Tunnel Ram or a Fabricated Tunnel Ram or BBC Stack Injection ( the version where the stacks didn't run vertical, but on slight angles away from each other ) Fantastic Engine
Would this Engine run on USA 🇺🇸 93 Octane/ 🇦🇺 🪃 🇦🇺 Australian 98 Octane ??? Thx 4 responding should u have the time ⏲️
Good content!
Most people don't realize that you can run that high compression on the street. I ran similar setups years ago that had even higher compression, but leaded 104 octane gas was still available all over the place. (showing my age, lol) The best result I got on the street, was oddly on a destroked 454 that was 408ish ci. I got 1.9 hp per ci out of it..... The key, is that the cam kept the dynamic compression in check, and the small ci extended the rpm range. I don't think that engine would have run so well on 87 octane, but the same theory applies. There were more than a few companies back then that made BBC Marine solid roller cams as low as 102. Lunati probably still offers off the shelf grinds to 106, and possibly lower in the custom range. Depends on the blank design, just as David mentioned...... It can get crazy expensive for custom cams that use custom cores....
This will be interesting! 👍
Awesome Result David 👏 😅
GM only made 1004 hp & 874 tq from there 632 .
Fantastic Work
“Prooven” is not a word David.
Fantastic 😍!
I have watched this twice and I can't figure out how you got it to make power at such a high rpm with such a small cam. I did read that right, the durations listed were advertised, not at .050, right? Something like 275/288 (dont remember the 3rd digit) Is it just compression and head flow? Those numbers don't seem possible with that amount of cubic inches with that cam.
Properly matched parts and efficiency
heat will be issue with high compression ?
You call 270's and 280's@ .050 a streetable low rpm camshaft???
Hi David, how much dynamic compression is ideal to run with methanol with a small block Chevy? I'm not allowed to run water injection.
At least 12.5:1
@@funfun8095 goodness gracious me. I'm running static compression at 14 to 1. My engine in the previous setup was only 12 to 1 with a fairly short duration cam with a 106 degree love separation angle. The old cam would actually yield that sort of dynamic compression. I was expecting to have to change the cam . Sweet.
Would it run on 87 without the water injection
Not sure I would call that a street engine ... Our 500 cid at just 10 to 1 makes 700 ft lbs at a peak of 3700 rpm
D.V. If its a streetable engine compared to a diesel, would it be a good engine capable for hauling and towing or would it get too hot? Also, would a solid roller be good for hauling and towing say in a 383 sbc? Thanks
This is a fantastic video.
You may have said on the video and I didn't see it, but is this a 93 octane engine?
Yeah no he says its an 87 octane engine in the video
David i am building a 429 boss what cams works best for street and strip not Mutch talk is done about these heads im using john kassie heads what are the advantages and disadvantages of sed heads
what is the cam # ?
This is and will always be the case with Crate motors. They are just a starting point for real performance.
Will this engine fit in my C7 Stingray?
GM sells a 1000hp big block pump gas engine. I thought you were in on that with GM.
Price that!
@@funfun8095 I can imagine.
Dyno flog here 20:26
Hit that like button
I might buy THE BEAST
Just to use as a display in my office:)
Then I can say things like..dot dot dot
“Get you tobacco juice bottles off my engine!”
lol
So ???? What about turbo charged with water meth injection would it get even better ???? Great stuff David always like being one of your students ! 😎🇺🇸
It has something to do with rod ratio or angle with a 632 that is not ideal for it to be turbo charged. But, Steve Morris has a video on twin turbo 632
@@mikefoley7561 I currently have a 496 100 over set up for turbo’s in my 67 SS Chevelle about 91/2 to 1 but I’m probably not going that direction because of space so wish I were higher compression now but I’ll probably go with water meth injection and half av gas solid roller for now thanks for the reply I do watch Steve he’s really 😎👍🇺🇸
Swirl. I'm guessing
A diesel engine does not produce higher torque than a petrol engine. Show a single diesel with 100 NM or more torque per 1000cc, of course without supercharging
H20 injection? Meth injection
Yep
Can someone explain what h20 injection is because I'm retarded and don't understand too good. I'm on the certified autistic spectrum.
@@j.g.bloodworth9837 water injected into the engine cools down the fuel charge and prevents detonation. not a new thing, has been going since at least WW2.
Water injection I won't to learn more on this I wished there was R&D dyno with this type of research going on 1 can dream ! I really injoy making and finding HP it runs in my blood sense I was a baby !!
@@rickybailey7123 Enjoy! SMH Research it! Like said above. It's been around since WWII, just like superchargers and nitrous.
I cant watch this guy cabt stand the way he talks
Thank you DV! v/r wh
Is this motor still available ?
Do you have a build sheet for that engine build?
Great video..👍
