INSTRUCTIONS
• 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 #2151 on engines
operating from idle to 5500 rpm. The Performer Olds 455 manifold #2151 and Performer-Plus camshaft #2152 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 Olds 455 Power Package components are used with the following
equipment:
•
Performer Olds 455 manifold/camshaft/timing set/valve springs
•
Original Equipment Quadrajet carburetor (w/electric choke) or Edelbrock carburetor #1407 or #1411
•
1-3/4" headers
•
aftermarket/re-curved distributors
•
any combination of the above
• 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 your dealer immediately).
