The reason that I'm asking again is because I have conflicting information. Some guys say yes and some say no. From a guy on the Tri-Five Forum he said the following --- The R terminal provides a full 12V to the ignition coil during cranking, bypassing the ballast resistor.
On 55-56 cars, this function is handled by the ignition switch, and if you have an R terminal, it is not needed. From other sources, I understand that this arrangement changed in 1957 on Chevys. But for my 56 Belair it is not needed.
