Mopar 350 Stroker

Are the pistons stamped as .060 over OR is the actually 3.910 + .060 measured? If your going by a piston stamped as .060 AND it's a chevy piston on a chevy con-rod combo, this is starting to smell like the chevy 283 piston @ 3.875 + .060 = 3.935 bore instead, which is only a .025 overbore. FYI the 283 piston is about 1.790 comp distance.
