• PLEASE study these instructions carefully before installing your new camshaft. If you have any questions or problems, do not hesitate to call our
Technical Hotline at: 1-800-416-8628.
• CAMSHAFT: Edelbrock Performer-Plus camshafts are ground specifically for use with the corresponding Performer manifold. The Performer mani-
fold #2156, and Performer-Plus camshaft #2157, are designed to work as a team to give you better driveability and performance. They are dyno-
matched and street-proven. For best results, use the Edelbrock manifold/camshaft package with the carburetor and headers we recommend.
NOTE: Maximum performance is achieved when the Edelbrock Performer Power Package components are used with the following equipment:
• Performer manifold/camshaft/timing set/valve springs
• Performer Series carburetor #1405, #1406, or #1407
• fuel delivery system of sufficient capacity
• IMPORTANT: This instruction sheet provides general installation guidelines which can affect your warranty. Read it carefully. It is not our intent to
cover each detail of installation here; a step-by-step procedure manual would be far too lengthy. We want to caution you that installing a
camshaft is a complicated procedure that requires a good general knowledge of automotive engines. If you are not confident that you can com-
plete the camshaft installation successfully, we suggest you consider having it installed by an experienced mechanic.
CAUTION: Improper installation will result in LOW MILEAGE, POOR PERFORMANCE, COSTLY REINSTALLATION, and ENGINE DAMAGE.
TO AVOID THESE PROBLEMS YOU MUST DO THE FOLLOWING:
Carefully study and understand all instructions.
Examine the camshaft for possible shipping damage (if damaged contact you dealer immediately).

• SPECIAL INSTRUCTIONS With the Edelbrock manifold and camshaft package plus a header installation, a carburetor jet change may be required for best performance. Due to the varied applications of year and model of vehicles, no one combination could suffice for all installations. The following procedure is only a guideline and in many cases, the manufacturing specifications for recommended carburetors or timing may be best. - Page 4 • WARNING In order for this Performer-Plus cam and lifter kit to be covered under ANY WARRANTY you MUST use the correct Edelbrock Sure Seat Valve Springs. The end flap or label from your Sure Seat Valve Spring box must be sent in with your camshaft warranty card.
