~450hp from stock stroke 340?

This is the part that always get me with threads like this. You want 450 HP or more from a stoke stroke crankshaft, but it's street car, so drivability is a must.

That requires at least 1.32 HP per cubic inch, and while achieving that is possible, it's not going to have street manners. I suppose it's all relative to what you call street manners.

Build a 416" and you only need to make 1.08 HP per cubic inch.

Exactly. The 500 HP 327 chevy from 1980 is still the king, even though a 500 HP anything back then was impressive. And very few of those were even 400 HP.

I can do 450 on 340 inches. In fact, I'm probably going to go over 500. And that's with some shitty parts.

Most guys wouldn't want to drive it because they will already have in their mind its too radical to be drivable.

@lead69 I think ran my engine through one of his engine programs and it was 540 HP or something.

I doubt it will get there. 500 is more than I originally started out shooting for. I want a nice, clean 11.60 car. At this point I probably overshot that ET by a little.
