I have two cars now that run better with the coil wires reversed from what the Mopar conversion kit schematic calls for! Both are chrome box installations but two different coil brands. Also one is small block and one is big block. That's afu . Oh and I thought I'd mention I repositioned my Duster's distributor drive shaft to the proper position when I changed the distributor . I had moved my cap wires to fit the one - tooth - off position that I had it stuck in.
