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

Tnx very much .....that is even further outside of the range of standard steels than the 340 pin. How did you measure the displacement? If you wold care to share the dimensions, I'll put that into my spreadsheet and compare the results. 16 ml seems in the 'typical' range for volume.

good info. you are correct, the density of steels varies. there are dozens of different grades of ferrous alloys. varying percentages of iron, chrome , vanadium, molybdenum, nickel, carbon etc.

Yes, but 6.6 is way outside of the range of common steels; that is the one I'd like to figure out.
