ok so i was cleaning up a 351 ui just got and the guy i got it from said it has forged pistons but i dont know if they are or not.

not even sure on the brand. but here are some numbers i found on the inside of one of the skirts.

L2378F30, 55b, tz

on top of the piston it has .030 so i know its been bored but i reall want to know what kind of pistons these are. knowing my luck they are some crappy cast ones.

suposed to be .040 forged I know yours are .030 but it should be the same..
 
hey josh where did you find that picture? those look real close to mine. mine has 4 of those cuts though. and that littl circle in the pic you posted is bigger. but it has the same outer dish as the ones in that picture.
