Dear jokunen:

The clearances in the Packard manual are for tin plated pistons with expansion struts. These features are no longer available. Thus, do not use the specs in the manual.

Your machinist should have the guideline clearances for cast pistons. I know for forged units the clearance is .0025.

I was on the phone to EGGE today about some pistons and they want slots toward the camshaft. I'll have to check if they use an offset.
