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.

Need some good info...

Default Need some good info...

My best friend just acquired a 1974 Plymouth Trailduster! Since he is not mechanically inclined, I just became the man in charge of building this rig. It has the 318 motor and auto-tranny. He has some moderate plans for it, but since I am new to this type of vehicle, I am looking for help. Once completed, it will be his daily driver here in Boise. We are looking for reliability along with cosmetic upgrades. I will be going through the whole thing from top to bottom.

Can you all point me in the right direction for a source of parts and things I need to look out for int he drivetrain/motor combo? We are already talking about converting to fuel injection and I know the NP-203 is a full time unit. I am unfamiliar with this transfer case. Does it even operate in 2 wheel drive? I know there is a part-time kit I can add, along with manual hubs for better mileage and drivability but is there a good source I can look to for this?

I had an 1985 Chevy in high school and college which I heavily modified so I am not afraid to tackle this project.

Any good sources of information or vendors.

Also, is there anything that is a "must-do" during the re-build?

Thanks!

Hi!

First, here is an article I wrote about the 203 that covers the major points and then some.

Also, in case you weren’t sure, it’s running the 727 transmission. Bullet proof – you won’t need to beef it up a bit.

For the rebuild (the 318, right?), I would consider a mild torque cam (I went with the Comp Cams 256h) and 1.88/1.60 valves in the heads. Those two upgrades will really punch up the power.
