need some help with block and trans ID????????

The block number is 2806830-3 I think it a 225 but I don't no what year it has the newer style head
The trans number is 6-97038
I was hoping the bellhousing would mate to a 833 but I'm starting to have my doubts I'm not even sure if its a mopar trans
I couldnt find any numbers on the bellhousing
Thanks Aaron
