I have a 96 LT1 with 60k miles, treated very well. Now, Ill be having LE2 heads and LE1 cam installed shortly, but i'd love an STS on there eventually at 5 (maybe 8psi)... good/bad idea? can this be done without forged internals? obviously ill be dropping the compression from 11.2 down to whatever and ill go meth just for good measure, but am I dreaming?

2nd, if I manage new forged internals, how much can the tranny and rear take? street tires and highway, no slicks or grippy takeoffs...

assuming I see 390rwhp, what could I expect adding a 5psi turbo on top?
