• PLEASE

study these instructions carefully before installing your new camshaft. If you have any questions or problems, do not hesi-

tate to call our

Technical Hotline at: 1-800-416-8628.

• CAMSHAFT:

Edelbrock Performer RPM camshafts are ground specifically for use with the corresponding Performer RPM mani-

fold. The Performer RPM manifold #7156, and Performer RPM camshaft #7157, 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 pack-
age with the carburetor and headers we recommend. The Performer RPM camshafts are designed for use with modified or RPM
cylinder heads, #6057-59 and valve train components only. Screw-in studs and H.P. adjustable rocker arms must be used.

NOTE:

Maximum performance is achieved only when the Edelbrock Performer RPM Power Package components are used with the

following equipment:
•

Performer RPM manifold/camshaft/timing set/valve springs

•

Performer Series carburetor #1407

•

fuel delivery system of sufficient capacity

•

1-3/4" headers

•

aftermarket/re-curved distributors

• 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 complete the camshaft installation successfully, we suggest you consider having it installed by an experi-
enced 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).
