Very Good Info. Would like to know how the .50 overdrive with the 4.56 rear works out?
What RPM does it go down highway at 70MPH?
Thanks

With my 26" rear tires, in 6th gear (0.50) at 70 the engine is only turning a casual 2063 RPMs. At 75mph it's 2210RPMs, and at 65mph its 1910RPM in 6th gear. Moving out from a stop with the 4.56's is a rush, and engine braking has never been easier ! I wanted 4.11's in the rear, ideally, though couldn't pass up the deal on the fresh 4.56 12 bolt.
