Its cool to hear you have knowledge with factory harness, you talked about the 318 magnum engine, and that got me thinking. I have an engine I got from Summit back in 2005. It was called a Magnum 380 crate motor. Its really a production Magnum 360, but has 380 hp, with 411 torque. This crate motor came with Mopar performance 4 bbl intake, and suggested a 750 carb, and not recommended for A/C. The add in Summit said it has bosses for fuel injection?? What does that mean? Can you remove the intake and convert to late model EFI? It has a strong cam. I just wondered if its a production performance engine, any chance Mopar might have software in place for this specific set up?
