Mopar (Piston Wrist-Pin Off-Set)
Just adding a little 'early performance tip' information.
The 'Factory Pistons' were built with an 'Off-Set Wrist-Pin' to help prevent
piston slap during cold starts.
But, as 'MOPER' stated, after-market Pistons were machined with a 'Center-Positioned' Wrist-Pin.
Back in the day, reversing the Stock Factory Cast Pistons (left-bank to right-bank and right-bank to left-bank)
was supposed to be 'The Trick', for less friction and higher RPM's.
