What do the new pistons give you?

If I replaced the SF rods with regular forged rods, what would I be legal for? (STS, STX, ESP, SM?) [some people think it's a rod thing]

What do you mean by "max level?"

If I did the rebuild, it would be to the max allowed within stock category rules (which is what STS allows). So, actually, my earlier ".040 inch" statement is wrong. Stock only allows .020 inch overbore. Street Prepared allows a bit over .040 as well as port matching and no more than .010 off the deck.
