Cyl pressures on 9/10 sec stock/forged short block SB C5s?

My question is what is your power adder, ( Super/Turbo charger, Cam/heads/gear/TC etc.), compression and what cylinder pressures are you running?

no c5, but i plugged my projected info thru a calculator i found online somewhere and came up w/ 470psi. not sure how accurate that is
have a trusted calculator? what do you think max safe cylinder pressure would be?
