one of the guys i went to highschool with had a 24 valve die on him, so he swapped in a screamin detroit just for S&G. not sure what model, but man is that thing LOUD. its a pullin truck, whole lotta show, not much go... beautiful truck tho

 

Id go with the 6.7 block and 5.9 head. Add the second charger and see where your EGTs are before adding more fuel. And actually if it was me, Id just rebuild the 5.9, twin it, and go from there.

 

Cummins or Detroit diesel.

I would love to see a Twin turbo 6V53 is a newer style truck.

Two stroke for the win! Just don't ever plan on passing emissions.

 

that would be sweet. the more i hear and learn aboot the two-smokers, i want one. it'd be hefty tho
