SCORE !! Went by the shop today and the bellhousing is a 3733365
But best was the guy says its scrap so take it home for free. Will check the dia of the opening as I would like to keep my old 4 speed. Looks like the opening is 4 5/8 hope that is gona work. Well looking at this further it is probably a car bellhousing, there are 2 bolt holes holding the motor mounts and my truck has one. maybe this was not as good of a score.
