[QUOTE="na svt, post: 12376081, member: 35346"] The GT cams have only 197 deg duration and are a downgrade to the 99 cams which have 202 deg duration. The 96-98 cobra cams have 204 deg duration but will only provide minimal gains over the 99 cams. The Cobra R cams do have more duration but the also require new valve springs because of their higher lift. The 5.8 as stated earlier does not have variable cam timing. GT cams can be used with stock valve springs. Also, the power on any n/a combo with a stock intake manifold will fall off at 6200, regardless of the camshaft's duration. The 2011 GT500 has the GT cams, prior to that they used same cams as all 03/04 4.6s (Mach, Aviator, Marauder and Cobra) and also all 4v Navigators. [/QUOTE]
