well i plan on doing some track time this summer. I heard putting some gears on these trucks makes a big difference. I don't do much freeway driving. once in a blue moon. I have just Intake as a mod and a muffler back.I plan on adding long tubes, a tune and a 100shot. just want to get some good recommendations on a set of gears?

 

#1: you need to get a seperator plate from Mike Dunn

#2: 4.10 gears

#3: I've heard that the mercury marauder had a close ratio 4r70 maybe you could use parts from one of those cars and modify your 4r70W

 

4.10 gears for sure.
That will get you going off the line quicker.

You can run 456 if you want...I am running 456 with 4R70W with 30in rear tires there fine if you dont need to do a lot of freeway driving....other wise go 410
