Isn't Cummins the optional engine in Ford F-650's?
I just dont ever see Ford or GM having Cummins. I cant see it. If Im wrong, Ill eat crow. But I just dont see any circumstance where Ford or GM would go with the Cummins. Theyre too dead set on the V8 design, for some reason. Fords had the chance to start from scratch, and they went with a V8. GM started from scratch 10+ years ago (not sure when they started design work on the Dmax with Isuzu) and they went V8. GM has always been into V8s...well the last 55 years atleast
