GM HEI on Mopar,Does it work?

Thanks for the explanation but that is EXACTLY what I was asking. You keep calling this an HEI but that is NOT what it is. This is a proprietary module. I've been told it's popular "down under" as it evidently evolved in Holden vehicles. If that distributor is what you have (same as Skip White by the way) then the BM series module, so far as I know, is what you want.
