Re: piston clearance
Mine .004 to .005, but I usually go with the .005. That puts it in the .001 per inch of diameter.
I know the voices aren't real but damn they have some good ideas!

Re: piston clearance
What Mark says if the pistons are aluminum. If steel they can be a bit tighter.

Re: piston clearance
It depends on condition of the block: We thermal clean the engines so they get the heat transfer. We set our cylinders to their recommended 3 thousandths clearance and have never had and issue.
