The little 318 & Racer Brown's quality products

I am NOT believing one mediocre dyno test, that is not how research works. Even if it doesn't work, there is ZERO reason not to do it. Even if it doesn't make any gains, it's not hurting anything to have them flipped. If it does make gains then you got free power. 3 guys on a dyno with 1 engine do not trump what Chrysler engineers said. That's just my 2 cents

Here is the poop. Stock oem pistons are offset to one side for quiet operation. Minimal gains of a couple to five hp can be had by flipping them. For a street build, it isnt worth it to me taking a chance on cracking a piston on pressed pins to flip them.

IIRC engine masters did the piston flip with aftermarket performace pistons most of which do not have the offset anyway. So nothing to gain by the flip.
