Looking at the specs of those pistons...it probably for a R3 block with 9.20 deck height...small block chevy piston pin size also......the R3 block probably came at 3.91 or 4.00 bore

Could also go into a tall deck, long stroke, long rod deal. Also a .030 over stock 360 block. Think 4.125 or 4.250 stroke with a long rod. That 1/16-1/16-3/16 ring package is obsolete for a race deal, but a 418g. piston with light rods would make it pretty snappy. Looks like a nice piston for the money except for the ring package.
