Default 460 strength?

I picked up my new motor today for my 88 f250 Im goin to be rebuilding this winter. I got a complete and bone stock 89 7.5 out of a wrecked f350. I will be pulling it apart for a freshening and Im doing some other stuff as well. The short version is it will be getting a stock rebuild from the intake down but Im adding 52lb injectors,custom sheet metal upper intake with a single blade 90mm TB,Megasquirt stand alone ecm and a BW S475 75mm turbo. I want to run about 8psi since that should be an honest 100+ ftlb gain.

My question is will the stock cast pistons take a small beating or am I just playin with fire by throwing some boost at them? Anybody lean on a stock shortblock hard around here? Nitrous? Blowers?
