One more thing. The maximum (legal) overbore for stock is .075" which means a .065-.070" oversized piston would be used.

Overbore both engines max (.075") and the 360 will gain more displacement because of the longer stroke.

A third thing, the longer stroke of the 360 means a lower rod-to-stroke ratio results in a piston that moves towards and away from TDC at a faster rate. This fact will only aide the piston-to-valve clearance in loooooong duration cams.
