Piston Pin Material - Unexpected

273-2 piston pin is a heavy wall to emulate the 318 polys piston bobweight as the crank was basically the same casting. Just measured a generic chevy size pins weight and area. The pin weighed 140.7g and the displacement was 16ml of water, so density of this pin was 140.7/16= 8.793g/cc

ha, that aint right. let me try something else....
.927 width*3 inch tall -.627 hole*3 inch=1.06 square inch total, weighing in at 140.7g...17.86cc= 7.877g/cc
