Old piston numbers

I have a chance to pick up a bunch of sets of pistons. Looks like some old stuff. One set that interested me were TRW part# L2224 .030 They are forged. Any idea what they fit? They also have a lot on NAPA numbers too. I appreciate any help. Charles

 

I think those are SBC pistons ...it's been awile since I worked at the machine shop but that # sounds familar...also I found out later,that there were alot of crossover between MFG. IE some small block chevy pistons also work in small block chrysler apps....the only tru way to find out would to be old parts books....good luck Shawn
