Such thing as a high revving V8 crate engine?

[Eli]

Or would it have to be custom built?

"high revving" = 8000RPM or more.

 

[Shawn]

that's pretty high even with a small engine

 

[imported_sling]

I've heard of people making a 383 stroker and using the left over small block 400 and 350 crankshaft in roundy round high rev cars. I think I have that right, 350 block + 400 crank = high torque, 400 block + 350 crank = high rpm. Do some looking around on that, I bet there's more too it than just a crank shaft swap, but that's the just of it.

I don't know if that would translate to 8k rpm either.

OK, how about 7500?

why do you want to rev your v8 that high for?

what is the application?

you could get a really big bigblock and then there is no need to rev the hell out of it.

building a v8 to run 8000+ rpm is a tough job. The forces at work on the reciprocating assembly are astounding.

LS7 but i dont think that is available as a crate engine.

I'll bet Eli fancies himself with the same engineering expertise as an F1 team.

 

[olds]

I have friends who race that go that high. Not sure if any/many street engines do.

 

[Sqube]

The real question is why you feel the need/desire to get your V8 revving to 8000 RPM. I mean... it's a V8. That's pretty beefy as is.

Indeed. You have to worry about things like the quality of the rods and rod bolts, the weight of the pistons and flywheel, windage trays, and whatnot. This is not to mention selecting the proper components in order to be able to actually make horsepower at those rpms (cam grinds, cylinder head design, intake/exhaust, and so forth).

No, you're not likely to find crate engines that will do this.

Ford's Cammer engine's redline is 7k.

I would imagine that GM Performance Parts has something available as a crate that would go as high as 6800 rpm, which is pretty darned good for $7000 with a 3/36 warranty.

Other than that, you would have to look for something from Lingenfelter or another builder shop that did a standard build, but look to pay upwards of $15,000.

If I might ask, why 8 grand RPM?

Agreed. Not many if any crate motors come with the titanium valve parts or fuel supply needed to spin that high. (And as you mentioned, cam grinds)

 

[compuwiz1]

You can buy any hot crate engine you want, but your cam is going to limit you. Also, I would not rev a non balanced and blue printed engine that high.

Take a look at the 572 Chev Crate engine, with 600 HP.

 

[Black88GTA]

Got $14,575?

Not quite 8k RPM, but...

930HP @7200 RPM :Q
760 ft-lbs @ 5500 RPM
555 cubic inches


Or, this 1160 HP monster
1160 HP @ 7000 RPM
950 ft-lbs @ 6000 RPM

632 C I

$21,995 :Q:Q

1700+HP with NOS Dual Pro Fogger as shown, not included.

Mother of God.

define "crate"

define what brand, engine, and useage.

For the street a V8 usually only sees about 5,000 rpm max.

Heck my car at 100 mph is only turning about 4,000 rpm.

 

[Eli]

LOL, I'm well aware of how difficult it is guys. It's certainly not impossible though.

Why 8k?... Because it would be unique, and it woud sound badass.

Chevy? 350? Usage?.... In my truck? Or maybe a 240Z?

Maybe I should have said "turn-key" instead of crate. Are there any engine builders that offer them for sale?

:roll:

lots of serious drag race engines rev like that. They are not streetable.

for the street I would shoot for 6000 - 6500 rpm max.

I will tell you that my 5500 rpm 318 sounds pretty damn sweet.

Why the roll? Is it wrong to enjoy the sound of an engine?

What do you mean "not streetable"? As in too much power? lol....

 

[Xionide]

Buy two honda v-tech engines like the b16a.

no, as in way too peaky a power band, too steep gears, serious overheating issues in traffic, lousy mileage (yeah, I know), parts that can and will break when you least espect them to, too loud (yeah, I know) and just too expensive.

 

[Black88GTA]

Here's one...8500 RPM.

Trouble is, it comes in a very pretty and incredibly expensive crate

The Ferrari F430's V8 can rev that high.
