GENERAL INSTRUCTIONS
• Please study these instructions carefully before you remove your stock camshaft. If you have any questions or problems, do not hesitate to con-
tact our Technical Hotline at: 1-800-416-8628.
• These instructions are designed to give general installation guidelines. A complete step-by-step procedure manual would require many pages. If
you are a novice or just learning to work on automotive engines, we recommend consulting either Chilton or Motors automotive manuals before
you begin. You may also wish to contact an experienced mechanic. Be advised: improper installation may result in LOW MILEAGE, POOR PERFOR-
MANCE, COSTLY REINSTALLATION AND EVEN ENGINE DAMAGE. Installing a camshaft is a complex procedure. Please follow these instructions
carefully. Failure to do so may void your warranty.
• Before you begin the removal and installation process, please examine the kit for possible shipping damage. If the camshaft is damaged, contact
your dealer immediately. Also, make sure you have all the recommended tools and parts as listed below. As you read through these instructions
the first time, use the preparation checklist to check off the exact items you will need.
• Performer-Plus camshafts are ground specifically for use with the corresponding Performer manifold #3701 (#3706 for 1987 engines). Both are
dyno-matched and street proven to work as a team; especially when matched with the Edelbrock Micro Plus ignition computer and Edelbrock
Tubular Exhaust Systems. However, the Performer camshaft package may be used by itself.

BEFORE BEGINNING: If the Air Conditioning condenser needs to be
removed to provide clearance for camshaft removal, have the system
evacuated by an appropriate repair facility BEFORE starting the installa-
tion. The same facility can recharge the system after installation.
REMOVAL OF ENGINE PARTS BEFORE CAMSHAFT INSTALLATION
Be sure to keep all parts in order. WARNING! DO NOT REMOVE RADIA-
TOR CAP OR RADIATOR HOSES WHILE ENGINE IS HOT!
1. Disconnect the battery.
2. Drain radiator coolant. Drain plug will normally be located on lower
right or left side of the radiator facing the engine.
3. Remove radiator and air conditioning condenser if so equipped. In
some cases, the front grille may have to be removed. Measure dis-
tance from front cover to grille or brackets that may interfere with
camshaft against the length of the camshaft.
4. Remove the gas cap to relieve pressure. Disconnect fuel line and
plug. Replace gas cap.
