If money is no object, go with some sub 9:1 JE or Ross pistons, some H-beam rods, and a 4340 crank. How much boost are you planning on runnin?

Definitely need some forged internals. An 8.5-9.0:1 static compression ratio should be ok for that amount of boost.

If money is no object, I'd be looking at doing a 383 with a Callies Racemaster 3.750 crank, Oliver Billet or forged 6" H-Beam rods, and some good JE or SRP pistons. Splayed 4 bolt mains, studs for the main caps and heads.

But that's just what I'd do.

I'd definetly get some 4 bolt caps, a good cam, hardened pushrods, heavy duty timing chain, and if you plan on going with more boost in the future, o-ring the block. You also probably want a deeper oil pan with more capacity. Just what I can think of right now.
