Re: WTB - 352" V8 Pistons .030" or .040"

I'd much rather have the .003 than the .0005 in any engine

It all depends on the specific expansion characteristics of the piston in question which is why the recommendation for clearance should come from the piston manufacturer; never use the factory clearance specifications for non-factory pistons, even those that might look physically similar.
