Gear upgraded, 3.08 to 4.10
I just upgraded the gear in my Suburban from 3.08 to 4.10! Still need to go to a speedo shop to get the speedometer calibrated. First drive today, it's feels quite a bit more responsive though it's...

I took my old F150 4.6L from 3.55 to 4.10. It made a HUGE difference. Unloaded highway mileage took a 1 mpg hit, but city driving and towing both had improved mileage. Not only that, I could suddenly maintain speeds towing in the mountains, and not have to worry about the truck grinding to a halt on long, steep climbs, which nearly did happen previously. It could suddenly cruise on the highway without dropping out of overdrive because a slight headwind or incline. The truck was so much more enjoyable to drive too. In short, it's the best mod I ever did to that truck, and I did a lot of them.
What transmission did the old Ford have?
