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. '72 440 Cuda 11.673 @ 115.91 w/1.663 60'

Which one will rev quicker? Which one will live longer? Which one is easier on the rod bolts...

It weights 190,4g (average weight of all 8) and it was measured with a 3000$ lab scale. The piston was 807g (in average) the snap ring was 5,6g (in average).

Yes a lighter piston is a much better option. However the 440 bottom end is very robust and many many people have used the trw for years with great luck. The rest of the combo you plan to build would be helpful.

I had to call Spped Pro, TRW, AKA Federal Mogul on a replacement piston that came form India with the dry film coating on it, it was lighter than the originals in the motor The Rep. said all of the machines had been moved to India and alll of the thier pistons where now being made in India It looked like a cast piston on the insides NOT GOOD Mr.Cab Racing and winning with Mopars since 1964.
