RE: Factory engine specs
Dodge themselves never made a 4x4 van at all. That doesnt mean you dont have one. that means that your chassis may have been sent to a company like Quigley Automotive, they put in the 4x4 drive train, and then sent it back to dodge for the body to be applied. Another method could be if somone did a body swap the only way to verify that would be to check that the vin on the engine matches the body.In the case of a Quigly conversion the engine and the body vin will match.
If you have a Quigley conversion, they generally hold a premium so you got a deal. Quigly stopped converting dodges in 94, the stated reason at the time was because of how Dodge placed the saddle gas tank made the conversion impossible.
