List and questions for a carbed 5.9 magnum swap

The Magnums all came with a "mini" starter unless you don't get one with the engine. Mid 90's Dodge RAM / Dakota 5.2 / 5.9 starter

You need whatever you'd use in an LA for a distributor for carb. "Keep the EFI" (thinks I)

Mags don't have a mech pump. Easy answer.........electric, rear mount pump

Consider keeping the EFI. There are ways to do factory, or use Megasquirt, and others.
'88-up RWD Chrysler (basically just not the D50, Conquest, Raider) on the starter. The one we usually use is '98 Durango just for consistency.

You'll need a car 360 pan and pickup- the truck stuff won't work in the Dart. Slants don't have the same bell pattern, it's integral on the autos so you'll need a v8 trans.

Consider keeping the EFI. It's not that bad to do the wiring and fuel pump, and the results are very nice.
