Chevrolet unveils its biggest, most powerful V8 engine.

Stuff it into a new Miata

While not a 1000HP BBC, it is a 700HP Hellcat:

 

[Bigtanker]

Here is a 1,000 hp Miata.

How much would an engine like this weigh?

Would you essentially a HD diesel truck transmission, driveshaft bits, and rear end to make it go?

Because it's an iron block, I would guess weight between 6-650lbs.

There are plenty of trans rated higher than 1000hp. There are even some 1000hp 700r4's which seems crazy to me.

 

[Jaybird1980]

Having built quite a few engines and a Chevy guy I would love to see one of these in person. Some things that stand out to me is the peak numbers are at fairly low RPM's. 1000hp at 6600rpm is pretty low.

I also see it's distributor less ignition. Looks like some LS style coil packs hiding under the air gap intake.

HMOG.

No replacement for displacement!

Wonder what it would do with a BDS screw blower on it?

With electric motors on the way that will match horsepower & beat torque, I'd say this might be the last 'Mountian Motor'...

So, where is the 70 Vega or 80 Chevette to stuff it into?
Can you fit it under the hood of a 70 Camaro? Chevelle?

Yup, I'm *THAT* generation...

That will fit between the fenders of most GM offerings and yes I agree our time draws close to its end.
But say what you will. A stupid fast electric car is fun to watch a couple of times but with out the thunder its really just not the same.

After market T-400's that live behind 4000K HP.

 

[Gunmetalgray]

I feel the need...

Modern tech in 60's muscle, match made in heaven.

Electric cars don't rattle the bleachers so much all women are horny after watching a few races!

Just like a rice grinder is never going to do to women what a Harley engine does.

 

[***Ironhead***]

Okay, who's going to stuff one of those in a Vega?!

I want to see one in a “smart car”.

 

[***Ironhead***]

yes.

This is the 462 BBC version.

Oops

Umm sorry but a 632 is NOT a Mountain Motor. Not even close unless you are talking 1980s technology.

 

[thunderchicken]

Why would anyone need a 10 liter, 1000 HP gas engine?

Because, **** you. That's why.

Well I am sure someone will put it into a street car of some kind and that's fine. But it is being marketed as a race only offering

Ok so many here know I'm not a Chevy guy but I applaud what they are trying to do here.
I'm a guy that has been around really fast door slammer drag cars for many years and I can't help but say what a FREAKING PIG!
Seriously, ANY 632 cubic inch "race" engine should make 1100-1200+ hp. I'll give a couple examples why I say that.
I have a friend who has a 585 cu in BBC (single carb) that's probably 20yrs old and makes 994 hp. We had a 588 cu in BBF (single carb)that made 1026 hp when we built it back in 2004. Then we had a 598 cu in BBF (single carb) that made 1198 hp. Now our 632+ cu in BBF makes 1200+ with dual carbs but the heads are a 30+ year old design (specifics are a secret). Many many drag racers have been running 632" chevy engines for a good 20 yrs now and I know a few who run E85 and make those kinds of hp numbers.

Edit- on our engines (588, 598 632+) those hp numbers are with no power adders. But, all were built to run on nitrous. So, due to cam profile they don't make as much hp as they would with a cam design for Naturally Aspirated.

It's got good stuff. I think the cam could be a little bigger just based off other comparable engines I've been around.

Well we are talking street here for the most part.
How big is musey building them these days.

The factory never gives you everything man. They never do.

I agree it's no barn burner compared to full tilt engines. The smaller cam specs suggest this thing is for more longevity to me. Would make a really good engine for a dragster.

Hyd roller is not letting it sing.
Full mechanical valve train and assorted other mods and Chickens numbers are attainable. It would push the power band north of 6600. Parts are stressed more. Longevity is compromised.

Mussi is north of 900 ci now.
