Those pistons are probably made for NHRA Stock or Super Stock applications...
The rules allow for .010 over stroke, making a OE 360 crank 3.59. it is stamped 3.59 so that the .067 or .070 deck Ht will be correct when the NHRA tech checks it in tear-down.
(of coarse the engine builder would know that.. it would be made up for, when the block is cut)
