I just bought a short block with .030 over pistons and they have 1738 cast on the underneath side. They are 4 valve relief and they are supposedly trw but i can't cross the number, i suspect they are a cheap set of cast piston from a northern kit.

All my TRW's have the numbers on the tops of them.
