I got a 1983 F150 4X4 automatic with a 7 inch lift and 33X12.50s. The gears in it now are 3.55s. When I start out and stomp on it, it just doesn't do it for me on the power until I hit 10 mph. The gears seem too high. I want more bottom end snort so should I go with 3.73s or 4.10s? Thanks in advance guys.

 

I'd go with 4.10s...you probably wouldn't feel much of a difference between 3.55s and 3.73s IMO
