So, maybe not the best idea, but with multiple drivers, I’m swapping my F350 to a C6. It has 628hp, locked f/r, 4.10’s, aggressive 36x14.50’s, 1.96:1 low range, ~6000lbs. What should I do to help it hold up? Local transmission guy, with good reputation, advises 3500 stall converter, and a manual valve body. Should I go with a low gear kit, low drag, change the planetary to E4OD? Not much experience here.
