I am replacing my old HEI in a 350. Put it to TDC, rotor pointing on #1 cylinder, and removed. I am installing an MSD Ready to Run. However, it will not seat with the rotor pointing at #1- its seated pointing at #4, and the timing mark is right around 0. Do I just need to make sure that with the cap installed, whatever terminal the rotor is pointing at, that wire goes to #1? I am not an engine expert, so any help is very much appreciated.
