I have a 1950 3100 that has a blown up 216 motor. I also have a 48 1 1/2 ton or 2 ton grain truck with what I belive has a 216 motor also. I was going to take the motor out of the grain truck and put it in the 3100 pickup but a mechanic told me that they had run into an issue a while back that the motors were not the same and woud not work in the 3100. Anyone know for sure if this is the case? Thanks,
