Camshaft help

You would be better off using the Comp Cam Part #12-238-2 Grind #XE262H-10 for your 350 engine. This camshaft makes more horsepower that the XE268H. The Xe262H operating range is 1300-5600 rpms. Low to mid range torque.

Rustey nut, you've got a pretty heavy vehicle with highway gears and tall tires. I would recommend a little milder cam than CD and Vinnie recommended. I would consider the Comp Cams #12-310-4 260AH-8 from Comp's "Specialty" or "Classic" line of cams. 444/444 lift, 260/268 advertised, 212/218 @ .050, ground on a 108* LSA. This is a pretty equivalent cam to the GMPP 350HO cam and the popular Summit K1103 cam. The milder duration will help keep your DCR up for low end torque, the 108* LSA will still give a noticeable idle. This cam would work well if you ever decide to upgrade to vortec heads with no mods needed to the heads. It's available at Pace Performance for $139.38.
