The bell housing is from a 48/49 to 51 Truck. It will fit a 226H or 254H Flathead 6. This bell/rear engine plate(or starter plate) will not interchange with the car components.
Are you talking about the V8 car components or are there differences between the car and truck H series components?
That does not look like the truck V* bell housing I have. It isn't that deep. Like someone said, it may be for a 6 banger.
