with all very large bore and stroke HEMI'S I own
there's not much that translates from what an SS Hemi pistion is shaped like.By using a 4.5" bore and stroke 4.5" or 4 3/4". everything we spoke about changes considerably.
nor have anything I would consider trick in the SS world.

However I did pull these from a trash can when after INDY when a Barton motor came apart in an SS car. what strikes me here is the out of the box appearance and far from what I expeceted to see from one of their motors.Later I learned this was not one of their "A" combos and no likely to have the trick stuff.
