One thing to check, is that the car has the proper thermostat and that it is installed properly. The earlier cars used one with a lower temperature (75C) while on later V-8s, I think this was increased to 80C.
BTW - When cars are converted to R134a, it is recommended by some, that the electric fan be wired to come on whenever the A/C is on.
If car is overheating, it may be worthwhile checking the timing. It may be retarded or the centrifugal advance may be stuck. (I would forget the factory specs and set it so it is so it is close to 30 deg BTDC at 3000rpm with no vacuum.)
