How much boost...
 

Workin on a 94 ford lightning, got a powerdyne supercharger for it, how much boost will the stock hypereuctic pistons hold? Id like to get 10-12 lbs if possible, not much just enough to wake it up a bit, it is a street truck that will see some passes at the track.

10 PSI boost ought to wake it up nicely, not sure if those hypers are up to the task though.
Was the motor rebuilt? That motor came with Forged psiton from the factory.
