Not without major fabrication.
In order to know what the value of a 1968 Chevy pickup is worth, you will need to know more details about the truck. You will need to know the condition and miles of the vehicle.
Not without modifications.
Yes it can, you will also need the big block pickup tube
There was a 396 available in all Chevy trucks from 1968 - 1970.
It uses full frame construction, much like a pickup truck does, but with a less substantial frame. In other words, the frame is completely separate from the body itself. The body is bolted to the frame but NOT integrated with it.
The rated curb weight of the 1968 Ford Ranchero was 3,451 pounds. The Ranchero was on a automobile frame with a pickup like box in the rear.
2-22-2009 The ElCamino wheel base is 117.5 A great frame to use is 1988-UP Chevy/GMC short bed pickup. The best frame to use is 1995 to 1999 Chevy/GMC Tahoe 4 door frame. It has a longer flat section that fits better under the long ElCamino doors. Both frames are 117.5 wheel base and are boxed in the front (great for big block) with more up to date components and parts are cheap. They also came with several motor packages. you could use an 1981 chev shortbox truck 4x4 frame they are pretty close
a little more clarification is needed. which wires are you talking about? the ones on the engine or on the body/frame.
If, by ECU you mean "Engine Control Unit", I don't believe a 1968 dodge pickup had one.
