A later engine with bearing insert and full oil pressure would be nice and so would be a 261. What later engines would be a straight bolt in swap? The simple answer is that there are some adjustments to be made when changing to a any high-pressure 235 (or any 261) in a 1946 truck. The easiest swap would be a 1954 or 1955st series 235/261. The only "adaptations" needed in those years would be to use a water pump, harmonic balancer, and generator with pulleys that match.
