Nice skirt design. Too bad more forged options don't have longer skirts like those.

It should be one very nice GE motor for sure.

I'd reccomend a thermal barrier coating for the crown if your going to run the No2 and high compression.. Just less expensive than melting a piston, especially one that you can't replace easy anymore. ;)

The moly on the skirts if you want, but the thermal barrier on the crown will really help to limit hot spots with all those angles, and keep the heat out of the piston as much as possible. (Heck, all three is best, but the crown coating is better than nothing IMHO.)
