1939 Dodge 89 dakota chassis swap and V6 or 5.2

Picked up a 89 Dakota today for a chassis swap on the 39 pickup, on the fence on the engine though the V6 runs decent. I do have a couple 5.2 Magnums here, are they a direct bolt in. The trans will work with a 5.2 correct? Frame mounts in the right location or do the need to be moved for the 5.2? If I do go the 5.2 route I would change the intake and go with a carb on it. What wiring would the trans need to work correct, its a auto with OD.

I started with a 4 cylinder truck and then made mounts for a set of spool mounts I had laying around for a 360. Files are to big for here so I could email you mine if you would like.

I had to move the motor & trans back on the Dakota frame so the 39 cab & front sheet metal would be in the proper location. I removed a V6 stick and installed a 5.9 gas motor with the electronic controlled auto trans. Just set the mounts to whatever location you need for what ever motor your going to use as you move them rearward. The thing that should be of concern, if you intend on using the 39 truck sheet metal, would be the length of the 5.2 compared to the 3.9 compared to the original flathead 6. The 3.9 will be closer to the same length as the flathead but the 5,2 will be longer. I had to widen the original relief in the firewall to match the V8, and I had to move the radiator forward into the grill housing a couple inches so there was clearance for the V8.

I can't understand for the life of me why all these Mopar people think they need to keep putting carbs on these EFI motors! 89 was the last year of production carbs used by Mopar, and they were crap carbs with a lot of issues. The fuel injection has been in use for many years and most are without problems. If you think you need to put a carb on it, I suppose its your ride.
The trans was pretty simple in 89. I don't believe the computer had any control over it, other then maybe the OD. Most of the electronic stuff on the 89 trans was so the computer knew the vehicle was moving. Gene

Does anyone make a stand alone harness for a 5.2 like they do for LS engines that doesn't cost more than I paid for the truck?

How much did you pay for the truck??? Probably not.

The Hot Wire harness isn't cheap, but by the time to get an intake, a new carb, a distributor, and fuel pump that will work for the carb, the Hot Wire harness is probably comparable. www.hotwireauto.com

You could resource a 5.2 harness out of a 92-96 5.2 Dakota, there is info right here on Moparts on how to modify that harness. Gene
