fromt he 5.0 HO engine how do the stock parts compair to aftermarket. I have no intentions to stroke the engine so i have no compelling reason to change them. On the other hand i want to rev over 6,500 on a modest supercharger and am not opposed to a 150 shot of nitrous. I don't want a weak link to save money, nor do i want to money away just because.

There's been more then one completely stock 5.0 shortblock that's live in the 9 second range. But not for a long time. I'd say the stockblocks that came with fordged pistons are fairly tough for a factory piece. But any motor running nitros should be using a good quality Hypereutectic or fordged piston for the 150 shot. I don't think I'd push the 6,500 rpm range, I'd stick with no more then 6,000 rpm.

Go with forged pistons, ARP rod bolts, and main studs, and a main stud girdle....Then the lower end will hold up to the 6500 rpm's

Depends on the age and condition of your engine. The most recent 5.0Ls had hypereutectic pistons as stock.
