• Please study these instructions carefully before you remove your stock camshaft. If you have any questions or problems, do not hesitate to contact
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 PERFORMANCE,
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 #2101 or #3701. Both are dyno-matched and
street proven to work as a team; especially when matched with Edelbrock Tubular Exhaust Systems. However, the Performer camshaft may be used
by itself. Edelbrock Performer-Plus cam #2103 is street legal in all 50 states - E.O.#D-215-19.

- Page 3 IMPORTANT NOTE: When using Performer-Link True Rolling timing chain and gear sets (#7800 or #7802) with an Edelbrock cam and lifter kit, straight up timing alignment is achieved. If any other timing gear set is used, it is necessary to check camshaft position for correct timing align- ment.
- Page 4 #7802. Do not use late model timing sets. They are machined in a retarded position and are not recommended for this camshaft instal- lation. Edelbrock Performer-Link True Rolling Timing Sets feature three keyways for specific timing selection. Always use the “0” or straight-up timing mark when installing Performer-Plus camshafts with Performer-Link Timing Sets.
