I am going to get a good dyno tune but just wondering what I could expect I have a m6 96 trans am 355cb forged speed pro pistons 10.5:1 long tube headers 1.6 rr and slighty ported stock heads and I'm going with a custom ground cam by Ai 230 / 238 - .566" / .566"

LOL Nobody can guess the exact numbers but it should be strong as hell especially if your backing it up with some low gears.

Which dyno? Mustang or Dynojet? I'll call 400 on the Mustang 415+ on the Dynojet.

All depends on the head work done and if it was done right. Why such low compression... i wouldve tried to bump it to atleast 11-11.5:1 as your leaving free power on the table. I think either way it could meet your goals if the heads flow good and your tune is on the money. Good luck and post up your results when your done!

I'll never understand how people can acquire a compression ratio just by the piston type without considering head gasket thickness, deck height, bore, etc.

Really just a guessing game at this point...what is 385 horse 376 torque to many variables. All there is to go on is the cam specs really. Post up results and let us know who wins!
