HEI in Mopar ECU casing

Awesome guys thanks for the input. This is all just a fun hot rod trial for me. Trailbeast, did you end up sticking with this HEI or did you end up going the route of doing the GM style HEI where everything is in the dizzy? If I recall you sell something like that. Any discernible difference in it all? I unfortunately just bought a new chrome box and a Rev N Nator coil and am kind of wishing I had gone the HEI route instead. I am very new to stuff like this so correct me if I'm wrong, but I didn't think you can ground to aluminum. Am I wrong in this or am I just thinking about it not being magnetic?

RedFish are you talking about the module under the dizzy like what Matt did? I think guys have had good results from it.
