I let a friend have this NOS set of TRWs to do a 416 deal, and the supposedly double throw down wingding FE expert shop can's figure out the ring package (with the pistons in hand), and they are 45 miles from me now. These are the basic "390 pickup" pistons, only question should be if the second ring is 5/64 or 3/32? I told him to ask the expert if he didn't have a caliper so he could measure the ring lands and the guy got real huffy
I know I have an old TRW catalog somewhere but can't find it, anyone have one, a cross reference or know for sure what package they take? My guess is the guy is just pi$$ed because he didn't get to sell my friend a set of pistons lol
