The Edelbrock Performer RPM Camshaft Kit for Harley-Davidson Twin Cam engines is designed to improve peak horsepower yet retain a broad torque range and improved rideability from 2800-6000+ RPM. Used in the Edelbrock Performer RPM Power Package, these cams have supported over 100hp at the wheels on a 95” Twin Cam. Before Beginning the Installation Procedure, Please Read the Following: NOTE: Due to the amount of special tools and expertise required, we highly recommend that a qualified mechanic or dealer should perform the following procedures which are covered in the Harley-Davidson Service Manual. INSTALLATION PROCEDURE : 1. Disconnect the battery, and remove the fuel tank. 2. On engines with the oil tank above the engine, drain the engine oil. 3. Remove the front exhaust pipe to clear the Cam Housing Cover. 4. Remove the Rocker Covers and remove the four 5/16” bolts and the two 1/4” bolts holding the rocker arms in place. With the rocker arms removed, remove the stock push rods. With all bolts removed, remove the cam support plate and camshaft assembly. (Note: Be careful the oil pump rotors do not fall out. Remove support plate with care, and make sure the oil pump rotors are still in place after removal. If the rotors fall out, see your Factory Service Manual for assembly procedures.) Verify the camshaft alignment using a straight-edge (See Figure 8). Re-install the snap ring onto the front camshaft, and check the camshaft alignment again. Re-install the Cam Bearing Retaining Plate, making sure the threads of the Torx bolts are clean, using a drop of blue Loctite on the threads of each bolt. Torque the Torx bolts to 20-30 inch lbs.
