I just bought a 1963 SWB and it has a 230 engine that does smoke quite a bit. I am considering rebiulding the 230, installing a different inline 6 (230,250 or 292) or installing a small block. If my 230 was in good running order could I drive my truck at interstate speeds (ca 75-80 mph)? Is the 230 stronger than the previous 235 engine (high Torque version)? I have had the truck since Wednesday and a link with pictures is below. Does anyone know of a good engine rebuilder in Northern Colorado or Western Nebraska?
