I was not pointing any fingers at anyone, so please do not take it that way. There were just alot of posts taht starting saying "pump gas this" and "race gas that" along with "HP here" and "torque that" "X amount of money" and "street use z" and "race car only" etc.... Just alot of info that started getting mixed up with the wrong motors and the people who build them is all, and I was jsut trying to clarify on teh Sonny Leonard motor I was talking about. That's it.

To answer your question though:
Comparing a 632" BBC to this 802" monster, is no comparison really. They are two COMPLETELY different engines, and nothing will interchange. The damn deck height on teh 802" is ALMOST 12"!! It comes in at a whopping 11.985. The bore spacing is 5" (the 892 CI motor uses a 5.30 bore spacing block) Pushrods are 1/2" dia. The list goes on. Basically everything on this motor, aside from a few parts, gets whittled out on an inhouse CNC machine.

Now, don't get me wrong, that type of $$$ is high, and when you can get, as you said, a motor that makes ALMOST as much power for alot less, I would definitely look into it. However, if you could see a pic of that "little" 632" next to the 802", it comes down to "look at mine" Think about it......do you REALLY need 1400 HP on the street???

 

yes, yes I do.

 

I'm with Slammer!

 

Here you go Gen. Sorry about the quality, I took a pic of a magazine page!

 

mountain motors = win, i'm sorry, i love FI and all, but there's just something about that RAW power.....

 

1400hp in a street car sounds fun.... cops would probably pull u over just to look at it hahaha

 

And I am with all of you guys as well. IF, I could afford that motor, and that is a pretty big IF, I would love to have it as well. Cuz even though we don't NEED 1400 HP on teh street, it sure would be

But as that pic shows (thanks Zac), look at the difference in the motors....it is like a midget motor next to that Mountain motor!!

 

Talking about the ~1,100 hp 800ci. Why would anyone want that bigger dimensional engine, when it makes a little less power than the Bishoff 632ci. Is there something about that bigger sized engine that makes it better for drag racing. I don't see why anyone would choose that bigger, heavier engien over the smaller, lighter, more powerful one, and save ~$50,000. Reliability isn't any better, no?

And damn....1,400 hp + a 250 shot....FUN!!!!

 

The 802 CI motor did not make 1100, it made 1417 HP. Why would they want it?? TORQUE!!! And gobs of it. And again, comparing the 632 to the 802 is not a fair comparison. I have NOT looked at teh 632, but what I CAN tell you is the 802 CI motor is gonna make more HP/Torque throughout the RPM range, apples to apples. You show me the tech sheet on that 632, and we will compare it to the 802....cam, compression, etc....and see how it comes out then.

 

Oh, I thought we were talking about two different big inch engines, one that made around 1,100 for 60K and then the 800ci for 80K.

I was wondering why anyone would want the 60K engine when the 632ci makes more power, for $24,000.

But jeezuz.....1,417 hp N/A....holy mother of pearl would that be fun to whip out on a 1,100 hp turbo Supra out on the highway.

edit: the 762ci 1,150 hp, 60K, thats the one I was confusing with the 800ci.

 

picked up this issue yesterday, absolutely insane, i want to see that *****'s when it's done!

 

OK, now we are making more sense here. And that is why I was trying to get specifics out, so we could apples to apples it.

yeah, 1417 HP, NA!!! I have not mentioned his 2,072 HP, NA motor yet, did I? Yeah, let me say that again, 2,072 fawkin HP, NATURALLY ASPIRATED. It makes 1,444 LB-ft NA That one comes in at a SMALL 892 CI, haha!

 

Holy shitkickers. 2,072 N/A, thats sick.

But the 632 and that 762 could actually be pout into a street car, I know that 632 can quite easily, maybe that 762 needs an old school big type of muscle car to fit it in.

But for drag racing purposes only....why would anyone want to pay 60K for that 762 that makes less power than that 632. Is there something unique to it that makes it better for drag racing, even with a little less power. I mean its got to be something pretty advantages because it costs $35,000 more than the 632.

 

Just to clearify, that picture I posted is the 892ci., 5.300 bore spacing, 2072 hp mill!!! It's also a pump gas motor. It's 87k.

 

Here you guys go, read this while I go change my shorts.

Sonny's also has a 932ci. mill on the 5.3in bore spacing block
5.080 bore x 5.750 stroke
2140hp @ 8100RPM
1475lbft @ 6500rpm
However this is not Pump gas friendly ringing in at 16.0:1 cp.
It's also aluminum rods, so no go on the street : (
Still cool though, almost a 1000ci.

 

7548fpm mean piston speed at 8100....makes the 6345fpm mean piston speed of an 8700rpm 4.5 stroke LS look like a walk in the park The funny thing is you could take a photo of this 932 aluminum rod/piston, scale it to the same size as a 427 LS aluminum rod/piston, and it will look much the same.

 

So is this motor!!! The 802CI one is run on 89 OCTANE, and is going into a *****'s coupe, FOR THE STREET!!!

 

The car made more like 550 - 560ish to the wheels through a powerglide and a non-locking converter. Also, once the gearing and tranny issues are worked out, it should run 9's on motor pretty easy since its already trapping around 140mph. As for a nitrous run.... should be pretty nasty

 

A local guy here pulled out a Brodix 1803 headed, single four barrel 632" engine and put a 706" with the same heads back in in his 3200 lb. '69 Camaro. It only picked up one tenth in the E.T. department and less than two mph. No street car can plant that much torque on any kind of street tire, drag radial or not. My son has a 598" BBC and can churn slicks if they are not heated first. A couple hundred more h.p. more would make any drag race merely a contest of who's car will bite the best. When nitrous is added the same 3565 lb. Chevelle can leave big black tracks when the juice comes in full blast and it has 3.50 gears.

 

Why is that?
