Jett Y. - Gen III LQ9 6.0

Champ Motorsports helped me out so much. I've always wanted to start building engines but was never confident I would do it right or buy all the right parts. This website helped me find every part I needed and gave me instructions on how to install my Sloppy Stage 3 camshaft kit into my 6.0.

The Sloppy Stage 2 camshaft kit gave my 5.3 a great choppy idle and helped my engine make power when I stepped on it.
