Cam question
 

So my orginal plans were to build a nitrous motor. I might buy a supercharger, f1 used. My cam was ground for nitrous and specs out at 242/246, .621/.621 on a 113 lsa. It was for a 383. Here is a run down of the build..
383 ls6
Compustar crank and rods
diamond pistons, which I will change to lower compression.
A.I. 226 243's
Arp studs throughout
Vengeance ported 102 and tb
Kooks 1 7/8" headers

I figure if I go this route I will use a lonnies dual pump kit for fuel. Bob at brutespeed has given me some suggestions on other parts. I would like to make 675 to 700rwhp through the 4l60 and when I convert to a 4l80 turn it up and shoot for closer to 800. What are your thoughts on this cam and my goals. At what point will I need to look at adding meth or something similiar? I will run this on 93 octane. What compression ratio would you guys shoot for?

Come on guys, I know there are some supercharger guru's on here.
