I have a small six that is being used as an irrigation engine. I need to rebuild it this winter and aren't for sure what it is. When I go to get parts for it if I tell the auto stores its out of a 68 bronco, what I've gotten fits( coil, distributor cap, points, etc) Its a one piece head, 4 water pump bolts, 3 freeze plugs. Manifolds are on rt side (what would be passenger side if it were in a vehicle). Starter is what I'd call high mount. Any ideas what beast I have?
