Hey guys, yesterday I bought a 2004 Silverado 1500 ext cab with a 5.3. Will post pics soon, but it's blue with 18" wheels and a dual exhaust. Just bought it, so I haven't done anything much to it yet, but definetly doing some reading up on it. What do you guys think it should run 1/4 mile-wise, stock? First plans are for a decent intake, then headers and a tune. Maybe down the line (when it's paid off, lol) I'm going to put a mild cam in it.
