Machine shop 440 Mopar questions?

One thing to think about is piston alloy as well. There's no way to finish hone a clearance without knowing what you're going to run, some need tighter clearance, some loser, the application matters, a boat with cast piston will need much more clearance, a drag car clearance will be different from which forged alloys used, hypereutectic wants tight a few tenths to half a thousandths. I'm still learning but I've learned this doing it over the last couple weeks.

I agree with what your saying but most piston manufacturers have moved towards making the bore size standard and the piston size to suit the material it is made of. Still I would prefer to have the pistons in hand before machining but that's not always possible. Some pistons have a coating on the skirts that doesn't allow you to measure them. The manufacturer just tells you the finish bore size.
