2005 Sierra Denali with a custom EPS grind 222/226 on a 114 comp cam. This video shows the first start. It was a cold start and idle hadn't settled yet. Idle will e set to afround 700 RPM to try and get a little more lope out of it. Current mods are the K&N intake, American Racing headers with off road mid pipes, GMPP cat back exhaust, and the cam with supporting mods like valve springs and push rods. TBSS intake and track times to come. This truck ran a 14.3 before the cam.
did u ever take it to the track?
