This SOHC Camshaft is designed for 1996-2004 4.6L two valve V8 Mustangs with 3.23 to 3.55 rear gears and will work with the factory tune.
If you're looking to get more power out of your SOHC 4.6L then consider a set of Comp Cams XE268H Camshafts. They will give you good low to mid-range power gains in both horsepower and torque.
Comp Cams are designed for modified cars that include upgraded valve springs for clearance related issues. It is recommended to use COMP Cams® 26113 Valve Springs for proper fitment. Combine the valve springs with a new set of valve spring steel retainers to handle the higher pressures developed by the springs.
