If you do go the delete route, be aware that you'll probably blow the transmission at some point. Stock transmissions were not designed to handle that kind of serious power. You'll have to get a built transmission or gearbox specifically designed to handle big horsepower (500+ HP) and that ain't cheap. I imagine you'll be using this as a work truck on your farm, so that probably won't be an issue for you.
Yes but stay close to stock tune and the trans will hopefully hold up.
We(the farm) bought a used 6.4 bale bed that was turned way up and it ate a transmission and rear end before we traded it off.
Crazy power while it lasted.
