I have also done some minor performance upgrades .In addition to these modifications I have also had a Transgo shift kit and corvette 1-2 shift servo installed in the trans. I've also installed a custom tuned PCM from Wester's Garage

A nice shot of my motor . It's a 4.3L V-6
I installed a set of JBA Cat4ward headers . These connect to a flowmaster 50 series muffler. These help the 4.3L V-6 exhale better .
Dual 3" chrome tips connected to a single in/dual out flowmaster 50 series muffler.
I also have a Airaid open element air intake .
I also installed a new throttle blade from CFM-Tech to increase air flow .You can see the difference between stock and CFM's in the picture.CFM Tech's Web Site
I'm also running a MSD 6A ignition system on my truck
I needed some new pics so I decided to go do a burnout .
