It makes an honest 400hp on the dyno and I still get an average of 15mpg. Ive got a lot of money into it to get there.
I would never even consider a cummins swap into my Ford! I just picked up a core 7.3 engine that I plan to build over the winter to hit the 500hp mark.
of course not ... why would anyone swap out a 7.3 motor?
swapping out a motor is a major PITA job that one would need a really good reason to do... like a dead 6.0
another trend for 12v Cummins swaps is taking super clean 1/2 ton gas trucks with low miles. end result is 28+ mpg dead nuts reliable truck that hauls ass with a huge jump in value $$.
