These cams are the top level of the Xtreme RPM series from Comp Cams and produce huge horsepower and torque gains in a massive RPM band all the way up 6200 rpm. These cams produce an extremely rough idle and require a huge host of other engine modifications, but can give you the winning edge on the track. This camshaft kit comes with four cams to fit the 4V DOHC heads of 1999 to 2004 SVT Cobras.
These versions of Comp's Xtreme rpm cams require a larger throttle body, bigger mass air, larger fuel injectors, exhaust upgrades like long tube headers, and PCM calibrations. Cobras with automatic transmissions will require a 2200 rpm stall torque converter. For more detailed information on these cams, check out their specification page.
