New Engine - Any Guesses?
To make a long story short, I had to build an engine from the ground up. Should be completed next week.
We're doing it with a lot of really nice parts and I'm curious what you might guess the power and torque of such a beast might be. So, on to the details:
LS1 aluminum block stroked to a 383 displacement
Forged crank, H connecting rods and pistons
AFR 230 heads
ARP 1 3/4" headers and high flow cats
C5R timing chain
High flow oil pump
Short track undersized pulley
Varam intake
Dewitt's dual core radiator with separate oil cooler
Elite catch can (I know, won't affect th power, but a good add on just the same!)
60lb injectors (I think they're 60... Bigger than stock anyway...)
Somewhat aggressive cam (I know, the specs would be REALLY helpful here, but I'm sitting in the back of an airplane as I type this and don't have the information with me... just assume its got good lift - but not too much, and good duration.
New C6 Kevlar clutch with remote bleeder
We are estimating the compression to be about 11.5
So, what's your guess?
If you're curious, the car is being built mostly for HPDE type events.
It also has:
Wilwood 6 piston brakes - front - the big ones, not the "lights"
Wilwood 4 piston rears
Pfadt fatty sway bars
Pfadt coil over springs
Pfadt camber adjustment
Caravaggio Rear spoiler
Race seats with 6 point harnesses
Runs 18" square (to fit those big brakes
Many thanks to Chuck - The man who really knows his Vettes...

Track wise, no way to tell since it would depend upon track and how good a driver you are.

Thanks guys!
I'm hoping that it'll be about 500 and 450 at the rear... As for the track... well, let's just say I get better each time. Oh, they were able to fix that wall I sorted "bumped" into
