Any idea about what this motors origin is ?
86 crewcab dually 454wth400 14 bolt rear end. The truck is revving to go 65mph on freeway. I'm running 215/75-16s and would like to be able to drive 80 like all the other crazies on the road! Any ideas about a good axle gear set to achieve this would be much appreciated.
I have a 95 extra cab dually , and 86 crew cab dually I'm restoring been a GMC guy for a long time, but don't know everything so it pays to network. So maybe I can offer help and I'm sure I'll need some. Hope to be a contributing member thank you
