yes if you have information on something other than 3.55 gears for the torque tube, please share that information, I have been looking for 2 years, and no one other than rickMG has found anything other than the stock 4.11, and patricks 3.55 gears. and he won't tell anyone where he got them. Yes you can turn the 216 6000 but you will have about $5000 into the engine.
