    Hey guys, I'm having trouble finding information on a set of pistons.

    Under the cap it says TRW above the wrist pin and under it says 262-99 with a J above that. Across the head of the pistons, right below the valve trough it has 336744.

    If anyone can help it would be great, Thanks!

    Are you sure those are the correct and the only numbers on the top of the piston?

    Kricka> Yep, those are the exact same pistons out of my 74 Z28 LT. Do you have a link to the part information by chance?

    Thanks man!

    Yeah, the nastyz28 page that they reference doesn't have my casting number on there. Oh well.

    Though I did find something else in the post that answered another question. Thanks man!
