I have a motor that came with my 1966 mustang and I'm not sure what year it is or what it came from. I also can't seem to find the casting numbers on it. Below the bolt closest to the transmission on the head there is a small 4 digit tag with screws in it and a what leads to be 33 E7TE and a a CA but that's it. The small tag says 8024 as well. The water pump on the motor has a casting number of E5ZE-8505-AA.

Can anyone help me out?
