Thank you for your math on the v8 engine offset.

The initial wrist pin offset was to make engines quieter in early days, that particilar offset was the opposite of centerline direction that the offset used to gain leverage and ultimately Horsepower.

It's always been a gray area and until someone comes forward with "they've been bounced for this, then anything goes in my opinion.

NHRA DOES check wrist pin location. Ask David Walther or Tom West. 1972 winners of div race at Muncie, IN until getting tossed for have stocker pistons in backwards. It's all been tried. Nothing new.
