The 289 and 302 engines are some of the most popular from the early Mustang. Whether you’re working on a restoration project or building a drag car, upgrading your camshaft and valvetrain can give you much more power.

COMP Cams has a wide variety of camshafts with optimized RPM ranges. Choose from mild to aggressive to suit the way you drive. These camshafts come as standalone components or as part of a kit. All-in-one kits come with complementary parts, such as timing chains and valve springs.

If you’re working on a total power upgrade for your Mustang, it’s best to go from back-to-front. This means installing exhaust upgrades first, then working your way towards the engine. A cam and tune should be the last items on your list.
