Looking for Info / Specs on Obsolete Mopar Piston

From internet forums (may not be accurate):

The old forged pistons from TRW required a pretty good amount of clearance. I think on the order of .004"-.006". Seen as high as .008" and RUN as high as .012". LMAO But that joker didnt burn a lick of oil because I file fit the rings. It was noisy when cold but got better when warm. Those old forgings are heavy and TOUGH. They can get by with some clearance.

Are the top rings .062" , or .078" ... if the top rings are .062" then part number is L2322F (P3690825 ?) a nice 662 gram piston with a 10.7cc dome volume, gives 12.1/1 with a 68cc head.
