Just looking at it , one would say 331 Cadillac to a early ford. Tim
I've have a strange bell housing I acquired a couple years ago. Looks like a 49-50 Merc stamped intermediate bell housing (8BA front bolt pattern, early Ford trans rear bolt pattern) only it's a little over a half inch deeper? Nobody has been able to tell me what it fits.
Attached is a photo of a strange bellhousing. An early V-8 transmission will bolt up to it , but I have no idea what motor it goes to, but I suspect it might be a tractor. Seeking a possible answer.
This is a 1948 H series 6 cyl bell housing.
