Anyone have an idea what a set of used trw l2210a std pistons are worth? Should original pistons have a gm number or a trw number? Thanks.

I believe there are 11-1 and 12 1/2-1 pistons. Do you know which ones you have ?

No i do not know if they are 11-1 or 12.5-1, on the top reads std l2210a trw and they are numbered, inside under the wrist pin is 186-99

Too many variables to guess a value like condition, which version they are, etc. In my opinion .030 pistons would be worth a bit more since most blocks that are 40 years old aren't going to clean up std. If they aren't worn & measure out to be still within spec maybe $100-$200 for the set.

Okay, thanks for your help..

yeah, i made a post a few months ago, and basically these pistons arent worth selling
