I have an 05 5.3 silverado ext cab. Its a z71 4x4 with stock 3.42 gears, stock converter, lpp long tubes, airaid intake tube, and custom diablew tune. I want to get 4.10's and a looser converter (3k maybe) and a cam.

Should I get my cam now or should I install the gears and stall first and wait on the cam?

 

If you cam it first it will be a dog until you get up to speed but for roll racing it would be fine. Gears and converter will really wake it up from a dig and it will be faster through the 1/8 at least. I'd do gears and converter no question!

 

The converter will be the most notable mod you will do out of the 3 you listed.
