Quick photo comparison of Mean Streak pistons 1500vs.1600

The original 1500 mean streak had many higher output engine parts. I'm putting them together with the 1600 crank, rods, and jugs. I just wanted to share the difference in the piston dish. The 1500MS (9.0/1) is almost a flat-top while the 1600's have more dish to maintain 9.0/1 along with the longer stroke. The standard 98-00 Vulcan 1500 was 8.6/1.

Using the flat-top piston in the 1600 should yield about 9.5/1.
