Help identifying pistons!!

[ra_doliv]

Guys,

I posted a question a while ago about identifying the pistons installed by the PO when I pulled the heads. I finally pulled them and the pistons have a part number of L2450 and are 30 over. I believe (and pray) that this is a TRW older part number for a forged flat top with valve reliefs. Does anyone recognize this number? I did a Google search and came up with plenty of part numbers but no exact matches. The shortblock is older than 1987. I would appreciate any info any one has.

I have a 1983 TRW catalog and they list a L2450F as a forged stock type w/pressed pin for a 302.There isn't a listing for just a L2450 in my catalog.It lists them as 8.5 comp ratio with a 69cc head and 8.9 with a 58cc head.
