Couple a coil questions...
1. I put a PS20 on a few weeks ago. The instructions were somewhat vague. Do I need to install the ceramic resistor block that comes with it? My 77 already has a larger block below the coil. I went ahead and put it in best according to the sheet, and the car runs great, but is it necessary?
2. I am really planning on a 6A or 6AL in the near future. When I do so, will I have to upgrade the coil? I am already kicking myself--the PS91 is only $59 and I paid nearly 40 for the little PS20.
