I have 426 apart restoration project,has pistons that I'm guessing were direct connection parts are part # 2531965 O/S, they are .005 oversize forged piston look like old TRW forging guessing that's mopar,dodge,plymouth direct connection part # since most all TRW #'s began w/ L.
Just curious if someone has some info,just want to make sure it's not a higher compression piston.
Balancing this thing everything in it is a chunk has a 3036.0 gram bobweight!!!

Were any of 426 external balance? All info I 've says internal
