What kind of piston is this?

[nswoperator]

I bought a 86 ttype project and the guy told me the motor had forged pistons in it. I just want to know if anybody knows what brand of pistons they are.I have have the build sheet from vansenus the number is sea l2481f30.I gave Vansenus a call and they would not give me the time of day.
Thanks, Matt

dont know why he needs to clarify , the part #s right there you have it L2481F and the size 30 (.030 oversize) do a search anywhere on the net
i dont need to because they are a common used piston for buick v6
# is for trw (speedpro/federal mogul) forged and the receipt already shows they are 30over

have them in my 87 , and what little i can see looks like them

ps heres what punching L2481F came up with on google , top of page
