Engine builders (Buick family) help ID pistons

I purchased the 72 GS 455 that was a Hawaii transplant back into Calf., then to Kansas. Anyway the engine had been rebuilt by a shop in Calf and had many performance mods done. A poston GS 118 cam, stall, intake, the engine was balanced and other mods. Something happened with the oiling and the engine was left disassembled when moved from Calf to Kanas.

Anyway my dilemma is I do not know the manufacturer of the piston and the specs. I was told 10.1 but I have no way to tell. There are some marking on them that maybe some of the Buick family might know more about these pistons.


Thanks for any help
