• VALVE SPRINGS
WARNING ABOUT YOUR WARRANTY:
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 or original equipment equivalent. Failure to install new Edelbrock valve springs or OE equivalent with your new Performer-Plus cam could cause the cam lobes to wear excessively and could cause additional engine damage.
1. This camshaft is designed to function with Edelbrock Sure
Seat valve springs #5814. Do not use dual valve springs with this camshaft. Recommended installed height for these springs is 1.700".
2. If using stock valve springs, check and set spring height to factory specifications for correct year and model. NOTE: Due to various settings throughout the years, we advise checking
Motors, Chilton, or Chevrolet/GMC service manuals or correct spring height for your vehicle.
• LIFTERS
1. Original equipment hydraulic roller lifters must be used with this camshaft. You may reuse your stock lifters after inspecting for flaws, scuffing, or any “grittiness” in the roller.
Replace as necessary with original equipment lifters from your dealer.
2. Check to be sure that all lifters fit freely in the lifter bores.
INSTALLATION INSTRUCTIONS
1. Coat cam lobes and bottoms of each lifter with MoS2 lube
(supplied) to prevent cam lobe and lifter wear from occurring during initial start-up. Do not "pump up" lifters before installation!
2. Install new camshaft and thrust plate with new sprockets, timing chain and lifters.
CAUTION: Use Edelbrock Performer-Plus True-Rolling Timing
Chain and Gear Set #7801. Do not use late model timing chain & gear sets that are designed in a retarded position and are not recommended for this camshaft installation. Use locking compound material on the bolt threads holding timing gear to cam. Torque to factory recommendations specified in motor repair manual (20-25 ft./lbs.).
Install camshaft with timing marks lined up as recommended by factory specifications (See Figure 1). Edelbrock Timing Sets feature three keyways for specific timing selection. Use the "0" or straight-up position for most applications. When using
Performer-Plus Timing Chain and Gear Set #7801 with Edelbrock cam and lifter kits, straight up timing alignment is achieved. If any other timing gear set is used, it is necessary to check cam position for correct timing alignment. This requires indexing the camshaft with a degree wheel to verify timing alignment. O.E.M.
or non-Edelbrock timing gear sets are not recommended for use with Edelbrock camshafts.
• INSTALLING PUSHRODS AND ROCKER ARMS
After the cam is installed and timed correctly (See Figure 1), it will be necessary to check each pushrod for correct lifter preload. Before installation, be sure to coat friction surfaces of pushrods, rocker arms and pivots with a suitable lubricant such as motor oil or assembly lube.
• VALVE ADJUSTMENT
1. Turn the engine over until the No. 1 cylinder is at Top Dead
Center (TDC) on the compression stroke (both lifters will be at the bottom of their travel in the lifter bores). Install No. 1 intake and exhaust pushrods, rocker arms, rocker arm pivot, and rocker stud nuts. Carefully tighten nuts while feeling pushrods for vertical clearance. As soon as all vertical clearance is gone from pushrods, tighten an additional 1/2 turn. This will provide 1/2 turn of lifter pre-load.
2. The above procedure assures correct lifter pre-load. Repeat this procedure for each of the other seven cylinders by rotating the engine 120° and following the firing order (1-6-
5-4-3-2). See Figure 2.
3. Re-install front cover, fuel pump, water pump, and oil pan using new gaskets.
4. Install intake manifold using new intake gasket set and torque manifold bolts to 25 ft./lbs.
5. Install crankshaft dampener and torque to factory specs.
• INSTALLING DISTRIBUTOR AND TIMING ENGINE
NOTE: Before installing your distributor, check the gear drive on the distributor and oil pump for any signs of wear. If worn, be sure to replace with new or you may wear out your camshaft prematurely. Edelbrock camshafts are designed to use OEM-type gears only.
1. Turn the engine over in the direction of rotation until the No.
1 intake valve closes and continue until the pointer on the front cover is approximately 5 degrees BTDC.

2. Re-install the distributor with the rotor pointing towards No.
1 terminal in the cap, and with the distributor housing in its original position.
3. Lightly tighten the hold-down clamp so that the distributor can still be turned to determine final setting using a timing light with the engine running.
4. Replace valve covers, carburetor linkage and remaining vacuum and electrical connections.
5. Reinstall air conditioner, if so equipped.
6. Refill radiator with coolant and re-connect battery.
7. Double check all connections, fuel lines, etc. before starting engine.
• CAMSHAFT/LIFTER RUN-IN
CAUTION: Change the engine oil and filter before start-up and again after initial break-in.
1. No lengthy cam/lifter break-in is required. The cold-start high idle setting is sufficient for initial break-in of this camshaft.
2. Start the engine and bring to break-in rpm.
IMPORTANT INSTRUCTIONS AFFECTING YOUR WARRANTY
• CAM LOBE WEAR - Cam lobe wear is almost non-existent unless mismatched parts are used or installation of the cam and lifters is done improperly. Most cam damage is caused by the timing gear coming loose due to improper torque on bolt. Bolts holding gear to camshaft should be torqued carefully and a locking compound applied to threads of bolts.
• CAM GEARS AND CAMSHAFT END PLAY - If cam gear becomes loose, the cam will slide back in the block, causing the lifters to hit the lobes next to them and also the cam bearing journals. If the engine is run after this happens, the bottom of the lifters and the sides of the lobes will become chipped. When installing a camshaft, it is always important to check for proper operating clearances, especially when high performance components are used. Things to look for that can cause failure and damaged parts are as follows:
1. Improper valve-to-piston clearance (this should be no less than 0.080”).
2. Rocker arm stud slot clearance (both ends; valve closed and open).
3. Proper spring settings (see dimensions with spring instruction sheet; correct dimensions mean maximum performance and longer engine life).
• IGNITION TIMING
Ignition timing for this package should be set at O.E.
specifications (refer to the timing information tag on your vehicle).
• EXHAUST SYSTEMS
For best performance, Edelbrock Tubular Exhaust Systems are recommended. These are available for most vehicles equipped with the 4.3L T.B.I. V6 engine (Blazers, Jimmys, Astro Vans, etc.).
Edelbrock RPM Series Cat-Back Exhaust Systems are also available for some applications, and will provide further improvements in performance.
