Like title says what you guys think my 2003 sierra 4x4 would run in the quarter. Think its will have a 13.9 or better in it.

 

Stock torque converter? If so, I think you'll run 13.7 or slower.

A mild converter(large diam 3000 stall) should put you in low-mid 13's and a loose converter(9.5-10.5" 3600+ stall) would yield high 12's-low 13's.

 

Yea forgot to add that stock converter for now if the 190,000 mile tranny makes it till spring I will get a circle d 3200

 

Your setup isn't far off from this guy's: https://www.performancetrucks.net/fo...0-08-a-473696/

His truck ran it's *** off!

 

I run a 215/222 .603/.596 115+3 in my LQ9

For a small cam it runs extremely strong. When using the vehicles I have ran for reference I would say its a low 13 second truck. I do have gears and a converter though.

I would say you should be a high 13 second truck with that cam and your mods. After the stall you should be mid/low 13's depending on traction.

 

I think tires and weight are going to be limiting factors for your setup. If you can drop some weight and have decent tires you can likely get the 13 sec slip you want. Lose the floor mats, jack, spare tire, tail gate, and anything you don't need. Every 100lbs will help you pick up a tenth.

 

Thanks for the replys guys. Beatdown that truck is why I settled on this cam. Dans truck flys for what's done to it I only hope mine runs that good now if I can just get the money for a dyno tune since my tuner doesn't want to mail tune it I'd be doing good. I don't run the 20s in my sig pic anymore gamble 265/75 on aluminum 16s a lot lighter than the 20s.
