Does anyone know how much the TRW L2355F six pak pistons weigh? I can't seem to find a weight for them or the 440 source pistons (part# 4000). .030 over 440 Ross pistons appear to be 647-658 grams depending on what you select.

I am just curious how much of a weight difference there would be between the Ross and the TRWs...and how the 440 source pistons would compare.
