I'm putting together a 78 block, 79 build date, 440 RV motor. Going into a 2wd Ramcharger.

I'm looking to bring the compression up and have a nice respectable cruiser/driver thats got a bit to play with once in awhile.

I found a set of new in the box TRW L2355f pistons. But it seems they are discontinued so specs on them are not easy to find.

They were originally purchased for the guys 70 440 6 pack superbee. But he went with a high compression piston instead.

These have been on a shelf for 20 or more years.
