A customer wants to use stock parts, but increase compression on a 2.7 clone motor.

He has heard that moving the wrist pin hole outward form the crank end -- effectively lengthening the rod -- gives approximately +1 (CR) per +1mm.

This is something we have no experience with, but it's clearly easier than cutting down the deck height, with its timing chain implications.

Anyone have experience with keeping stock pistons but boosting compression ratios?

Thanks!
