I would run a hypereutectic piston for any street car that makes less than 450 h.p.,above that I would look at a forged piston.Try Midwestmotorsportsinc.com for pistons.The last set of hypereutectic pistons I saw for a 350 where about $75 for a non-coated skirt version.You never said what heads you had.These pistons will give you about 8.4 to 1 with a 76 cc head.A lot of people talk about the (quench) area.For a (stocker type re-build) I would not even look at it.After all tens of thousands of engines come out of Detroit and other cities with out really being checked.I would just make sure that the block is not warped and and the heads are flat and call it good.I would look at cam's with less than 215 degree's duration at .050 if you run any more than that you will need to look at a looser stall plus you don't have the comp. ratio to support it.
