Somehow, I've missed what kind of truck that you have.
I know that you've just supercharged it and from some of
the posts about gear ratio, I seemed to have gotten the
impression that it was a 4x4 (?).
I can only offer some questions that I think you should
come up with answers for.
Is the truck your daily vehicle? If so, do you use it
more for highway driving or city driving?
Do you want it to be a street racer or a track racer?
If a drag racer, which is more important to you, ET or trap speed?
If ET, what time is your goal? If trap speed, what mph would
you like to hig?
Do you have some idea of your current hp and torque ratings?
Have you moved the power band into the higher regions of the
rpm scale?
Do you want to outrace an R/T? I would imagine you have higher
hp and torque than a stock/mildly modified R/T with the SC and
your current 3.90 gears.
In my case, the truck is a daily driver, more city than highway
travel. I'm also a weekend drag racer with a 14.9 and 90 mph goal.
With the truck's current weight and mods, a gear change from 3.55:1 SG
to 3.90:1 SG will probably allow me to reach these goals. A gear change
to 4.10:1 would almost be a certainty but I would not want to run
with these gears on the highway (even with my infrequent use of
highway driving). I've passed the stage of serious street racing
long ago so I'm satisfied with the truck's current specs.
Good luck in your decision.
