If you mean L-2377 ,they are Forged Big block chevrolet 454 pistons Made by TRW/Speedpro
They are low compression flat top around 7.5:1 with openchamber heads 8.5:1 with closed chamber
heads. Good for Blower ,turbo or nitrous.
Could be brought up to 9.5:1 with deck and head milling.

Sounds like you are in the same boat I am. I have a set of l-2244 pistons and no one seams to have any specs on them...
