nice project.

If you mount 2 motors inline, make sure one can freewheel while the other is turning.

Basically, put a sprag (high torque, obviously) between the first and second motors, so your constant drive motor is the one closest the transmission, and the motor further from the tranny (the "1st" motor), is used for extra torque when necessary, but won't drag down the first motor (it's not much drag, but it's drag).

You'll want to regear to take advantage of the excess torque that these motors produce, and the relatively low RPM's that they can work in. Probably better to keep the same transmission ratios, and re-gear the rear-end, to lengthen the final drive ratio.

Lighten up anything you can afford to. If you can afford a 1 piece fiberglass front end, go for it. Anything to save weight, or offset the weight of the new components.

BTW - Regarding the Ford Truck... That cap is definitely not helping it's range... LOL.
