5.9

You have 2 ways to go. 1. get the computer control module from the Durango for control of engine & trans. Or there is an aftermarket system for adapting to A-body electrics. You will also need electric fuel pump for the fuel injection. Trans mount and tunnel would have to be modified for
2. Get the front timing cover, water pump, pulleys, distributor, and fuel pump to convert engine to LA style. Also need oil pan and pickup tube for rear sump. Then get a trany for LA engine and convertor/flex plate for the 5.9L engine.
I went with conversion to LA style since I had a 318 engine for parts. Well worth the conversion.
