Well, being as there is only a 15 gram difference in piston weight and an 18 gram differential in the NHRA accepted weights, I doubt that in STOCK, reciprocating weight has anything to do with whether one will rev quicker than the other. In SUPERSTOCK, it's a moot point as you can make it as light as you dare.

Personally, I'd take the 400.
