Mopar (Piston Wrist-Pin Off-Set)

If memory serves correctly,

Back-In-The-Day.....

Both 'JE Pistons' and 'Forged-True Pistons' had '0' Off-Set in their Forged Pistons.

Even TRW #L2222N Forged Pistons were machined with '0' Off-Set.

The 'general theory' was, that the 'less friction' between the piston and cylinder wall
resulted in an increase in approximately 200 RPMS, and 15 More Horsepower in engines
with the 'Factory Cast Pistons'.
