ive got 4.10s

i have 4.10s on my 94 vert gt
i love the power and acceleration of it.
i dont think i would want to go any higher though just bcasue on the highway around 80 ish the rpms are kinda high and it wants to slow down a lot but there tight other than that

Ryan i'd check your speedo gear...you should be more like 2200-2300 with 3.73s unless your rear tires are really tall. I also wouldn't run anything less than 4.10s with an automatic.

I have 3.73`s with 3500+ stall and no lockup and 60mph is like 2600 rpm.
And if I had 4.10`s I would never get to the 1320 mark below 7000 rpm I also have a 26" tire (275x50x15 mt dr`s) I need 27 or 28".
If your going to go 4.10`s first think about what tire size you will have and converter stall and lockup or no lockup.

Ryan did you calibrate it after the gear swap? That would read faster than your actually going at a certain RPM?
