Looking to borrow or buy a single 273 4bbl commando piston

Thanks Toolmanmike.

I’m shootings for a 300+hp 273 and in an effort to gain HP they want to design a piston (if one is not available already) with custom ring gaps and 1/2 as much tension on the rings as a street car would normally have. Squaring up the cylinder and head alignment. Proper cylinder bore 0.040”
Bowl and port work on the heads and lightning of all rotating parts to get me there. It’s going to be fun!
