[QUOTE="snakeraper11b, post: 13074595, member: 128473"] For one, those are stock bore pistons. If your heart is set on them, you'll need part #MOD220571F00. With a 8.933 deck height and and bore of 3.572 (standard .020") those pistons will yield a compression of aproximately 10.35:1. It doesn't say anything about the wrist pin diameter, top ring down, ring spacing, or valve reliefs. If you ever want to put decent cams in it and degree the intake below 112, you'll need reliefs, something to think about. If you ever plan on boosting it or turning some rpm's, wrist pin diameter will come into play. My suggestion would be to go with diamond 30013's and upgrade to the .200" wall pins. The compression height of those is 1.230" vs the Mahle's at the oem height of 1.220" This will bring the piston .002" in the block before it's decked. Take off .004" for the deck and you're at .002" out of the hole. Pair those with some .043" compressed height head gaskets and you get 10.33:1 compression and piston to head clearance of .041", better that the oem .048", but not dangerously close for the forged manley H beams.
