I was running the old piston and if it was within spec for the wall to piston clearance then im going to run it agian.   The piston is a forged 55.5mm piston and its at like 55.36-55.4 range. so I just want to know what a forged piston usually runs for cylinder wall to piston clearance

.002” is common

Its what was specified on some custom pistons I’ve used. Also have seen .00185
