They fit them from a rather tight interferance to a slight clearance. Different...
Thanks for the tech specs. Never got around to checking into it. I was also vague on purpose, lol, if I said a full thou or more (and I didn't know exactly) someone would have argued. I was just generally informed with no exacts given.

Just to add, people have to keep in mind the cyl diameter itself expands also. In a marine app running ~70* coolant you need more piston to bore clearance(~.005 with 2618 pistons) due to the cool temp coolant keeping the cyl diameter from increasing.
