I found this bellhousing among some of my Dad's things and I am having a hard time identifying what it is for. There are no markings or casting numbers anywhere on the bellhousing. I thought that it might be for an earlier flathead Ford V-8 to a 1949-53 Ford transmission but I can't seem to find a flathead bellhousing that matches the bolt pattern. It also might be for a 1955-60 Pontiac engine to Ford transmission since my Dad did have a 57 Pontiac engine in his 1950 Ford but that doesn't seem like that is right since there is no provision for the starter on this bellhousing. Anybody have any ideas or suggestions?
