Supercharged LT1 383

Hello all, I am a newbie here and thought I'd see what I'd find.  I currently have a 93 Trans Am.  Here is a list of all its current upgrades:  
   
 195 Deg. Thermostat
MSD Ignition 6A and MSD Coil
3.73 Gears in the Rearend
Powerdyne Supercharger 4.5psi
Accel 24 Lb Injectors
Stage 2 Shift Kit
58mm BBK Throttle Body
Plugs NGK TR-6
Edelbrock Headers
BeCool 4 Core Aluminum Radiator
Ported Intake Throttlebody side only(to accept 58mm Throttle body)
Electric H2O pump
Lowering springs 1.5”
New MSD Distributor and Wires
New Stock Computer
Royal Purple Oil and ATF

The only mods I did were the new radiator and headers.  Everything else was on it when I bought it.  I have since lost a piston, and decided to go with a 383stroker for it.  I have tried to get ahold of Powerdyne to find out info on cam sizes and compression ratios that their superchargers work well with, but their number on the site leads ot a company called O2performance and they don't answer either.
Here are my questions:  
 What would be the recomended compression ratio be?  I was thinking 8.5:1.
 What size camshaft would be good? I would like to put in some 1.5 or 1.6 rockers as well.  
  Any help would be appreciated, and thanks in advance,
                                                                 Bob
