The rotating assemblies on those cars are really strong, I know of a guy with a stock bottom end SS with a TSP T-Rex cam and around a 200 shot, and he's putting over 550+ to the wheels easily. The only upgrade you should need to spray an LS1 is an 255 lph fuel pump and some computuer tuning to back a little timing out of the motor, a 150-175 shot should hold just fine.
