Summit Racing™ Pro LS Single Plane Camshafts
Summit Racing™ Pro LS Single Plane cams are affordable and designed for racing applications where a carburetor and open exhaust are commonly found. These cams have slightly narrower lobe separation to increase torque and compliment short runner intakes. They come in distinct cam timing increments to give you maximum control over the power band. They’re also designed with longevity in mind by taking stress off the valvetrain. These lobes remain stable to over 7,000 rpm with a common .600 and .670 lift dual spring kits.
