Rob....you didn't happen to experiment with that starter on your former Valiant with the small block and Dougs headers did you? My 65 Barracuda will be a 273, 998 trans, Dougs headers. I have, and planned on using a 90's Magnum motor mini starter....but ain't throwed all those parts together to see if it fits yet. Block is still in machine shop hell ! :BangHead:
