The pilot tip of the transmission measures ~17mm. , The number you get will be driveshaft revs per mile, which is the same as engine revs/mi if you don't have overdrive or torque comverter slip. As an example, let's say you have 31" tires and a 4.10 rear end, so: 20168/31 = 650.6 tire revs/mi. 650.6 x 4.10 = 2667. 2667 engine revs/mi. That is also your engine rpm at 60 mph., The 4:1 option would give you reduction gearing of 2.8:1, 4:1 and 11:1. (the 6.55 1st gear 465 ratio aside). I think this would be a happy combination. In fact you would probably be happy with a 5.7:1 1st gear ratio if you happened to be able to trade the SM465 for a H55 someday., 06 - 3500 Crew cab LLY/ZF-6 SBC Dual Disk sprung hub, PowerPup, killed the cat, muffler delete, finger stick, Autometer Cobalt EGT guage, Scanguage, Kleenoil bypass oil filtration, PCV re-routeAftermarket mirrrors, rhino lined and undercoat, nerf bars, firestone airbags, Reese Class V, 5th Wheel/Gooseneck.
