HEI in Mopar ECU casing

Ok, thanks for all the info. Thanks for the wiring showing Trailbeast. I plan to run a 4 pin just because I can do it for free. Are you guys running vacuum advance? I capped mine off years ago and it's always ran well without it. Good idea on the Mopar coil.

I'm ordering a chrome box today to get my car back and running normal again and will do this project at my leisure.
