I'm in the middle of assembling a pump gas 340 stroker motor with SRP pistons that have right at .0035 piston to cylinder wall clearances, those pistons rock from .0050 to .0080 on the cam side at the edge of the cylinders with a small screwdriver holding the piston tops towards the cam shruggy My old pump gas 400 srtoker motor had .035 with a .042 thick head gasket on both sides of the pistons, it was touching both head on both sides a tiny bit shruggy It didn't touch with .047 thick head gaskets after that thumbs
To many people on here preach things that don't work for me when it comes to clearances in motors we beat on work .0010 to much clearance are way safer then .00010 to little shruggy
Be safe thumbs
