Plowboy Diesel has created the ultimate dual-engine drag monster. The 1970 Dodge D-Series has two Cummins 6BT inline-cylinder engines fused together under the hood.
Engine Swap Depot reported that the two motors, which are each boosted by BorgWarner turbochargers, fuse back into a Track Master 47RE four-speed equipped with a custom gear box.
That setup needs a massive system to keep things cool. According to Car and Driver, that build takes a trio of icebox radiators mounted in the bed and a massive front-mounted intercooler.
The truck seems to be the mechanical embodiment of a "because I can" mentality.
