I n the diesel industry, Cummins swaps are nothing new. The B series inline-six has been the engine of choice for sled pullers, drag racers, rat rods, and (of course) Ford trucks for more than a decade. However, the unwritten rules of engagement in performing a Cummins swap dictate that Duramax-powered trucks are off limits. With common-rail injection and a proven track record for performance and durability, the 6.6L V8 is more than sufficient in yielding the kind of power most enthusiasts are after. Put simply: you just don’t go there.
