The tooling set up for the pistons will be set up for A SINGLE piston. NOT a set. A piston is a piston.

The tooling is set up for the LARGEST oversize. All lesser sizes down to standard are ground from the largest oversize.

So there would be only ONE mould set needed for 374 and a close but different mould set for the 352's.

So it's not really "sets". It's number of pistons that drive the cost vs demand. I don't know what a piston shop currently charges for grinding a piston. If he makes only .030 over pistons then one would have to have them ground to the smaller oversize if needed.

Some piston manufacturers supply pistons this way and they are called "Semi-finished" pistons. They only have to be ground to specific size application.
