One of my buddies is a Cummins mechanic, he said just rebuild it, more worth your time. So I'll take his word for it. Sense itll need injectors, should I get stockers or something over?
I plan to build this truck, auto will need attention, valve body upgrades are good till 400hp. What would I need to do transmission wise for 500+?
What about fuel side for 500+?
And turbo wise. Compounds or a 66?
