Im going to do a gear swap and probably a new stall. i was just wondering what kinda difference would going from 3:73's to 4:56 gears "running 33in tires" and like a 3000 stall converter would make? as far as get up and go and how much difference off 1/4 mile times?

 

is it dd?

 

yes sir, its a 2004 gmc sierra ext cab, 4x4. with a 5.3 fully bolted with nelson 91 tune... i have 33in tires and going to install 4:56 gears and maybe a 3000 stall

 

BIG Difference.
