HEI in Mopar ECU casing

My 78 LRT has a 1978 date coded Warrenty 360. The first owner said in the first 6 months it was in shop 3 times for oil leaks and on the 4th time the Dodge dealer ordered a new cop car 360. So not a numbers matching truck. But I am putting a 2008 (?) 5.9 Magnumn with Edelbrock RPM aluminum heads and shorty headers so it does not look stock now.

If this works out I will do a second for our 1965 B-cuda. I converted it to ECM back in 1987 or so.
