If you have a BBC with enough hp/torque to get the torque converter to lock in 4 gear can you tow in OD? Or is that still going to burn stuff up? My trailer weighs 10,000 lbs. that’s what my k3500 is rated to tow. I’m swapping a souped up 454 into it and am hoping to stay in higher gears for the duration of my haul. What should I do to the transmission to keep it from burning up? I’m thinking a torque converter with the stall speed of 1500 and an HD2 kit.
