Is it possible to get a 2004 CCSB 4wd into the 14's naturally aspirated? The truck is equipped with 5.3L, 4L60E, 3.73 gears, and the factory 265/70R17 tire/wheel combo.

So far the mods are an Autocal Black Bear 91+ tune, Airaid M.I.T., AEM panel filter (oem style, dry), and a Magnaflow 3" SI/SO muffler with a 14" long case.

I have the following parts, but they are not installed yet. 799 heads, DynaTech long tube 1 3/4" headers, DynaTech catted Y-Pipe, and a Corvette servo.

Am I off to a good start? Where would I be once I get the above parts installed, and get a re-tune?

 

A converter and cam swap imho

 

I would think those mods you have yet to install will get you into the 14s.

What does your truck run now?

 

New tune will help

 

Unfortunately, due to health issues, I haven't been able to run the truck.

There are two tracks close by, I just haven't been able to get there to get a baseline. One is a 1/4 mile and the other is an 1/8.
