COMP Cams XE278AH Xtreme Energy Camshaft Set with a 2200-6200 RPM Range for 1996-2004 GT Mustangs and 2001 Bullitts.

A best seller due to its excellent all-around performance in street applications. Increased responsiveness and more area under the curve are delivered due to quicker opening lobe profiles. More vacuum is created which allows a step up in duration for greater performance. COMP Cams roller rockers and matched valve springs work best with this camshaft. Other performance parts are required (intake manifold, headers, etc.) for best performance.

The XE278AH is a great street/strip camshaft. It delivers a rough idle and requires 3.73+ gears and a 2400+ stall torque converter. You will also need an intake, exhaust, computer and valve spring upgrade.
