supercharged lt1
I just bought an ATI p600b supercharger/intercooler for my 1993 Formula.
What cam would be good for 9 lbs of boost, and what some are good forged pistons to drop my compression ratio to 9:1. (stock heads for now)
I know a decent amount about cars, numbers arent my strong point though.

How much power do you want to make? That 600b won't go real far.
9psi is entirely relative - at 9-1 you may not be real impressed. On a good flowing top end it would be a different story.
Cam it the way you want to drive it. Superchargers don't mind a little overlap. If you want a 7k screaming setup with a rough idle, then buy a big cam. If you want it to drive nice then buy appropriately.
I'm going to assume stock displacement since you didn't say otherwise. SRP has a 24cc dish that will get you close, but a lot of people don't like them. Mahl has a better piston that is around the same dish that will do better but costs a bit more.

additional info
Yeah, I got the setup offf a guy for 1800 bucks, I know the d1sc and p1sc are better, but i couldnt pass it up. my friend has a mild 5.0 built and i have to whoop his car.
I just bought a racetronix fuel pump and harness(255L/Hr @ 43.5PSI @ 13.5V ) 42 lb injectors. Stock motor for now, but saving up for a 383 stroker kit(any suggestions). Gonna get another block and build that motor for more boost on the side. I just want to pump as much power as possible from what i got (i believe i got a good deal)
Im lookin for about 400 rwhp until the 383.

not at all, weekend cruiser, planning on forged internals, porting stock heads/intake, 3.42 rear gears, 9.5:1 compression, maybe 383 if budget allows.
Not putting it together unless i build it right

*update*
Waiting on student loans to come in. Going to have about 2 grand (probably a lil more) and I wanna go forged b/c I don't want to
What are your suggestions for a reasonably priced 350 (preferably) or 355 rotating assembly. i would like a 9.5:1 Comp. ratio with stock heads* and to have about 450 rwhp conservatively. I'm hoping for more
Its a 93 Formula A4 and my motor only has 24k on it so I do not believe I need to get it overbored. ( I put half of those gently driven miles on it :P)
I have a Procharger p600b w/ a 9 lb pulley (2 core intercooler), 42 lb injectors, Walbro 255 intank, Flowmaster 40 series 3 in catback, and stock everything else.
What exhaust would support my setup, I was thinking Pacesetter LT's into 3 or 4 inch single or 2.5 in true duals from what I read. On a budget, but I get to pump about 2 grand into my car every 6 months to a year. (tax returns rule!) I want to drive it as much as I can, so I am amassing parts b4 I put em on.
Learning more and more every day. The advice given to me earlier in this pist really helped. Just trying to plan my finances now.
*Heads
Would it be More cost effective to port the stock heads/intake, buy some decent used heads off of this site, or Edelbrocks Rpm xtreme 194 cc CNC lt4 Heads b/c they are 1029.50 a pair(267 cfm intake and 187 exhaust so I read)
Sorry for the long post, but i wanted to get as much info out there as I could.
