I have a set of 8 never used TRW pistons the part # is L2249N they Have a 12to1 comp. and are on new Ford standard length 302 rods. The pistons have all been installed with the dual snap ring locks and on a floating pin these are ready to go. I now have other build plans so i would be interested in trading for a set 1.7 roller rockers but open to many trades so send some offers. They are around 530 from summit so 300 shipped seems fair or trade Thanks I have some pics on my photobucket Pictures by gjohnson7291 - Photobucket
