My favorite “layout” for a dual rear wheel truck is exactly what you are looking at here. I like the “phantom” dually look with the eight foot fleetside bed and I love ’em with a standard cab. It is also likely the most useless layout for one of these trucks but we all like what we like and that’s how it goes. This truck punches all the right buttons for me. It sits right, has the cool late model wheels, I dig the white paint, it has no rust or other visible crappiness happening and then we get to the engine bay.
Obviously GM did not build fleetside dually trucks from the factory so this one is a person’s project. A person that left a 292 inline six and three speed manual transmission in the nose of this truck. I have plenty of personal experience with the 292 engine and love them like the draft horses that they are. Meant to work and work and work, they will do just that and likely until the end of time. They make little power, though and when you see a big square jaw dually like this one you are immediately thinking big block, right?
Obviously the swap would not take all that much work because the engines basically install themselves in these trucks but it must be weird hearing this thing going down the road with that screamy exhaust sound from the 292 coming from the dual tail pipes.
A 496, an M22, and a Gear Vendors would basically transform this thing into my dream truck. How would you “finish” it?
