Re Gearing
I want to swap my 3.55 gears for a set of 3.73's and i was wondering what kind of power difference can i expect. Id like to gain more torque out of the hole with this truck for pulling and for fun. I dont know if i theres enough of a differnce between the 3.55 and 3.73's to make a differnce. I assuming my millage wont change all that much due to the o/d. And with less work on the motor to get up to speed, might help maybe. Dont know though.

Personally, I would go with 4.10's, you won't notice alot of difference in the 3.55 and 3.73 gears. Even with 4.10's, in OD you only go up about 400rpm at 60mph.
If I ever get the cashola, I'll be changing my front and rears to 4.10's.
