So just to clarify, the ACTUAL stock cylinder of a 350 will measure 4.000 inches and therefore a piston that says it's bore is 4.000 will actually measure slightly smaller in order to fit inside the cylinder?

If I were to purchase new pistons for example from summitracing.com, and the piston specs say the bore is 4.000, will they fit inside a cylinder that is EXACTLY 4.000? They would have to be slightly smaller right? Sorry I'm just a little confused.

If I have my engine bored to .060 over, will I buy pistons that say .060 over or will they need to be smaller?
