Ok I have a 2002 Sierra with the 4.8 with the auto trans regular cab. I am going to have a transgo shift kit put in it the performance stage 2 kit, Have the CAI, and will be putting in a 3200 stall convertor as well. with those mods and a 125 shot on it with a tune what do you think this truck can do in the 1/4 mile with traction.

 

im gonna guess 14.50's?

 

ide think if you could hook it that it would go low 14s. thats if its a 125rwhp shot, the truck is surely pretty light.

 

If you spray outta the hole and cut a decent 60', then I think you'll be low 14's or better.
