The Truth about Gears and Tires

[WhiteRavenRR]

This is a great thread. I'm stuck in 3.8l thinking because I have a 3.8l. I will be looking at gears sometime in the future. I don't ever see myself going bigger than 35's so I'm thinking along the lines of 4.88. I'm running factory 4.10s in an automatic with a Dana 30. The supercharger would be an interesting addition to the fold. I would like to see some real world numbers for the 3.8l regarding gears with and without a supercharger.

Figure out if you are going to supercharge or turbo you truck. That will alter how you feel about gears.

Blower first.
