The best thing to do is make sure it is properly tuned, and the carb and choke are properly adjusted. That is as good as it gets. If you were to install a newer engine, then you are dealing with computers, sensors, solenoids. None of which your car was ever intended to have. It is possible, but the cost and work far out weigh the benefit.
