New to me Barracuda with Mopar Crate 390hp low oil pressure

Doing both. Fixing what needs fixed to enjoy the car and if I get offered a good price I will sell it. This is my first Barracuda, I actually wanted a Dart. The wife liked the Barracuda looks better and now so do I. I really think I want a manual transmission.

The 10 year discontinued Mopar fuel injection kit is a headache. Idle air control valve isn't a mopar part. After much research, it is a Holley thottle body which uses a holley IAC valve or a GM LS1 IAC. To further mix it up; the IAC parameter in the ECM need to be reset which I think happens once the ECM reads 40mph (thats what GM computers do. But the hodgepodge Cable to 90 degree adaptor into the electric conversion that also has an adaptor for the speed signal for ECM... Something in that system isn't working. IAC never adjust to learn idle position. So it is most likely staying part open even at cruise speed, which complicates tuning.

My local "custom" shop said it would just be best to remove the outdate system and go with Holley Sniper. Which I agree.
I get first dibb's on the car.
If you are going to flip the car put a carb on it and be done.
Pic's would be nice
