A good running Model A with the original 3.78 differential, no overdrive and no ait filter should be able to do 60 MPH on a level road with only the driver aboard. My Model A cruises at 55 MPH on the highway with two people aboard, There is enough throttle left to accelerate to 60+ MPH.

As for points and condenser, the original style is est for fit and reliability. The least reliable is the electronic stuff, and there is no advantage to modern points and condenser. The best spark plug choice is the Motorcraft TT10.
