Here is what I have, a 2003 z71, 5.3 volant CAI, ebay headers, gibson catback, Circle D 3200 converter, 210/218 .531 cam, ls6 springs, 285/70r16 tires(big issue I know), 3.73 gears, probably will go with a Black Bear tune. I bought my cam before my trans died and I bought the converter while it is out. How close will I be with the current setup and what should I do to get closer to my goal. Should I change my cam to a 220 and go with it or will I get there with the current cam and just drive it? I have the parts to go in but I haven't ran it with the cam yet. I have searched and cannot find 14 second trucks with a good description of mods to get to that point. I am open to suggestions before I put it back together. Thanks for any help.

 

i dont see why it wouldnt run low 14s with what you listed
Even on the bigger tires

 

Is this an EC RC or CC?

 

nitrous would get you there easy without changing cams or heads

 

If you're not there already, a set of 31" or shorter tires will probably get you there...

 

I would be kinda surprised if it didnt run 14s already.

Some 4.10s or 4.30s would be nice with those tires.

And a little bigger cam would help, you have enough converter for a 220 cam. IMO

 

Extended Cab, I know shorter tires would help, but it is my daily driver with those tires

 

I would really like 430 gears but that is a BIG expense that the wife would probably veto, after the trans and converter. I could do the cam cheap enough by selling mine and buying another, since I haven't installed it yet it would not be any more down time for me.

 

Is the cam in yet? And what do you run with the mods you have now?

 

i agree 220 cam would b nice
