So I don't have to be worried? That's a consolation Jerry.
What's a "flipped piston"????????
I got this fron Smokey Yunick (some old hot rod magazine artikel he wrote).
Our pistons have an offset pin to reduce piston slap - right?
In a nut shell: If you take the pin out and rotate the piston 180 degrees (so that notch/mark faces backwards instead of to the front) you change the (rod/crank) geometry, which Yunick states gets you some more power and "snappiness".
By reversing the piston, the rod is more upright on the way down (like a longer rod), pushing more directly on the crank, thus, slightly higher torque at certain points in the stroke. You pay for it with some piston chatter when cold though, also probably more wear.
