Plowboy Diesel's ’70 Dodge Pickup Proves Two Cummins Diesels Are Better Than One

Plowboy Diesel's dual-engine 1970 Dodge Sweptline Plowboy Diesel's ’70 Dodge Pickup Proves Two Cummins Diesels Are Better Than One Overheard near Plowboy Diesel's dual-engine 1970 Dodge Sweptline: "Why two Cummins diesels?" "Because three wouldn't fit." There's a certain logic to that, one has to admit. According to Plowboy, the build actually was inspired by a joke that the engine bay of early '70s Dodge pickups could fit two Cummins diesel engines. At least it was a joke—until the shop made it happen.

The concept is pretty straightforward. It is a 1970 Dodge farm truck with two Cummins diesels between its front wheels. All it required was a custom-fabricated frame, a new pair of sequential BorgWarner turbos for each engine, and a special gearbox that ties the two engines to a single transmission's input shaft, but who's counting steps?

To keep things running cool, a trio of Icebox radiators were added to the pickup bed to make room up front for a full-width intercooler behind the grille. The bed also is where dual sets of fuel filters stand exposed near the tailgate. The truck runs air brakes and an air-spring suspension, items that we imagine complete the drag-racing-schoolbuses soundtrack. Is there a point? We're not sure, but neither do we care. The truck has two engines. That's all you need to know, really.
