Ramcharger, Trailduster & Power Wagon Grrrr!! Tough Trucks! The Dodge Ramcharger and Plymouth Trailduster were full size SUV's that had good looks and brute strength. The Dodge Power Wagon was comparable to them in toughness, but came in pickup truck form only.

Default Power train swap, 1976 pw

I'm looking for some advice, I have a 93' dakota donor that I want to put the motor, Trans and need components in my 76' power wagon. My issue is that the transfer case in the dakota is abliveraited, I can get one out of a 85 d150 but don't know if it will bolt up or not? Dose any one know it it will?
any info would be greatly appreciated, thanks

It has the full time 4 wheel transfer case in it, I know that if I want to keep it I would have to get a adapter plate and a stub shaft in order to make it work, trying to do this project on a low budget

They came with full time 4WD can't put in a modern t case without a way to disconnect the front axle. They also came with 3 speed 727, Putting in an overdrive transmission you will have to move the transfer case back to make it fit. Then you will need drive shafts.

Just shifting the "new" t-case into 2wd will still work, just all the front end parts will still be turning in 2wd.

I rather liked the full-time 4wd in my blazer.... (also the NP203 t-case.) Just make sure you rear brakes are working properly.... I discovered mine were not one day when I went to stop in an icy parking lot... The front tires stopped turning, the rear tires, on the other hand, went twice as fast, and stuffed me into a concrete retaining wall...... I fixed the brakes that afternoon......

I am aware of the mods that will have to be done, I have all the parts to do the swap other then the transfer case the came with the power unit, it is cratered. But I have access to a transfer case out of a 85' d150 with a manual transmission, just need to know if that one will bolt up to the overdrive auto?

I would like to keep the full-time transfer in. My other option is to rebuild a 440 and the 727 Trans and stuff in it but if I do that then I'm going do a complete tare down of the truck and restore it, I'm just wanting to get a few more years out of it before I go to that extent

Where is the oil sump on your donor engine? I had a '77 Trailduster (Plymouth version of the RamCharger) with a 400. It needed a lot of love and I took my time sorting it out. Someone had dropped another 400 in it and instead of changing the oil pan and oil pickup to a rear sump, they "adjusted" the oil pan with a hammer. That resulted in oil starvation on the engine. The rear sump is necessary to clear the front pumpkin on the front end.

The donor engine is also out of a 4wd so the sump is on the rear of the block

Are you sure? I've seen center sump oil pans in 4X4 trucks. The Dakota is a totally different frame from the full sized frame. The 1976 was designed for a big block engine to fit, whether it was ordered or not. The first Dakotas were built 10 years after the last BB pickup.
