700HP 383 Buildup

Yep I'd have to agree with Moper about trying to get that kind of power out of a pump gas 383, I'm running 11.5 to 1's in mine.

But hold on, what does your buddy have done to his 350 chevy that makes it so radical?
Does he have high Compression pistons?
Does he have aluminum heads?
Did he stroke it to a 383ci?
What does it run in the quarter mile?
What car does he have it in, does the car have any fiberglass on it?
What size cam is he running?
I don't know if this is the case, but I've run into so many so called 500-600hp small block Chevys, then they get waxed by a low 13 second Mopar. There are some VERY tricked out small block Chevys out there that can pump out that kind of power, but unless you know for sure he may just be pulling your chain. Just something to check out.

ALso Check out the posts from 383man about his sons Dart. It has a 400ci motor. That will give ya an idea on what it will take to do 11's, also look what it did to a 454 Chevy at the track =)
