some pictures are kind of fuzzy. But looks like they are all the same. Backwards.

I have put together piston reversed for years on different engines, including Pontiacs, I could never really tell it made much difference anyplace. That includes noise, oil usage, or power.

I know of a 340 Mopar that someone took the engine apart, pulled rods and pistons out, took the free floating pins out of the factory pistons, flipped the pistons around so the offset was backwards from stock, reinstall the pistons in the same holes, with the same rings, on the same tune, and pickup up 2 tenths in the 1/4 mile. A 340 is not a 428, a 428 is not a SBC 400. There is a reason that became a well known speed trick, on some rare occasions it seemed to make a difference.

Mike there can be some valve terrain noise that come from running Rhoad's lifters. Make sure your ok with that before you go that direction. If your after an extremely quiet running engine, they probably are not for you.
