5.9
Addemdem to my post.
I was thinking LA engine when I wrote.
I am finishing up a 5,9 into a '79 Dodge Magnum now.
You'll sill need the engine mounts a d such as I listed before but for the engine, should you decide to forgo the FI parts, it's just a distributor, intake and carb you'll need. Headers optional.
I used a Eeelbrock RPM, 650 Thunder, MP vacuum advance distributor and hooker Super Comps. I didn't get the flywheel so I needed a B&M unit to mate to the Summit converter.
The Magnum engine is otherwise dead stock including the serpentine belt set up.
