I run a 10.5 @ 68.5mph stock .... weird. Maybe I have 4.10s already? How do I check? I know first gear shifts at 41mph @ 5500 rpms. What gear does that sound like?

The reason my is so slow right now is that my cam has moved my power band up in the 4.5 to 6000 rpm range with stock gears that leaves me with nothing on the low end. now once i get my gears installed it will be a different story.

Yeah its a 4wd, 4.8 auto. Pretty basic too, no power windows, manual 4wd, no carpet.
