• 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 (#2111). Both are dyno-matched and street
proven to work as a team; especially when matched with a 4-bbl. carburetor, an aftermarket or recurved distributor, and tubular exhaust system.
However, the Performer camshaft package may be used by itself.

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. Disconnect radiator, bypass and heater hoses.

position of the vacuum advance canister in relation to the manifold
assist getting the distributor properly located during reinstallation.

11. Remove carburetor and intake manifold. Remove and discard intake
manifold gasket.

12. Remove rocker arms and pushrods.

13. Remove hydraulic valve lifters.

14. Remove crankshaft pulley, and using a suitable puller, crankshaft
dampener.

15. Loosen oil pan and remove water pump and front cover.
NOTE: The front cover oil seal should be replaced before the front
cover is reinstalled.

16. Remove fuel pump and fuel pump push rod. Rotate engine until tim­ing marks are aligned as in Figure 1.

17. Remove bolts retaining camshaft sprocket. Remove sprocket and
chain.

18. Remove crank sprocket using a gear puller to remove sprocket.

19. Remove camshaft.

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 either the correct Edelbrock
Sure Seat valve springs or the stock original equipment valve
springs. Failure to do so could cause the cam lobes to wear exces­sively and could cause additional engine damage.

1. This camshaft is designed to function either with the stock springs
or with Edelbrock

Sure Seat

valve springs ,#5813 (std. retainer set)

or, for rotators, use #5913.

2. Check spring height and set to factory specifications for correct year
and model.

REMOVAL OF ENGINE PARTS BEFORE CAMSHAFT INSTALLATION

Be sure to keep all parts in order

WARNING! DO NOT REMOVE RADIATOR CAP OR RADIATOR HOSES WHILE ENGINE IS HOT!

Figure 2—Firing Order—1-6-5-4-3-2

DUE TO THE MANY POSSIBLE SETTINGS OVER THE YEARS, WE
ADVISE CHECKING MOTORS, CHILTON, OR FACTORY SERVICE MANU­ALS FOR CORRECT SPRING HEIGHT FOR YOUR VEHICLE.

LIFTERS

1. New lifters must be used with a new camshaft. Use only the lifters
supplied with your kit .

2. Check to make sure all lifters fit freely in lifter bores.
INSTALLATION—Coat cam lobes and bottoms of each lifter with
MOS2 lube supplied with your kit.
THIS WILL PREVENT CAM LOBE AND LIFTER WEAR FROM OCCUR­RING DURING INITIAL ENGINE START UP.

2. Install new camshaft with new sprockets and timing chain.

3. Use locking compound material on bolt threads holding gear to cam.
Torque to factory recommendations specified in motor repair manu­al.

4. Install camshaft with timing marks lined up as recommended by fac­tory specifications. See Figure 1.

PUSHROD AND ROCKER ARM INSTALLATION—After the cam is installed

and timed correctly (see Figure 1), install push rods, lifters and rock­er arms.

VALVE ADJUSTMENT

1. Turn the engine over until the No. 1 cylinder exhaust lifter starts to
move up. At this point install adjusting nut on intake rocker arm and
valve. From this point turn adjusting nut down (clockwise) 1/2 turn
more for final adjustment.

2. Turn the engine over again until the intake lifter just stops coming
down. At this point install adjusting nut on exhaust rocker arm and
adjust to zero clearance between rocker arm and valve. From this
turn, adjust nut down (clockwise) 1/2 turn more for final adjustment.

3. The above procedure assures correct hydraulic lifter preload. Repeat
this procedure for each of the other five cylinders.

4. Install front timing cover with new gasket.
NOTE: Install new seal to oil pan to front cover if old seal is damaged
after removal. Use RTV silicone on seal to ensure proper seal to pan.

5. Torque front timing cover bolts to 6-7 ft. lbs.

6. Install front harmonic balancer and torque to 60 ft.-lbs,.

7. Install fuel pump and push rod.

8. Install water pump using new gaskets and torque to 30 ft.-lbs.

9. Install intake manifold using new intake gasket set and torque bolts
to 25 ft/lbs.

DISTRIBUTOR INSTALLATION AND ENGINE TIMING

1. Turn the engine over in direction of rotation until the No. 1 intake
valve closes and continue until the pointer on the front cover is
approximately five degrees before top dead center (BTDC). See
Figure 2 for firing order.

2. Reinstall the distributor with the rotor pointing towards No. 1 termi­nal in the cap, and with the vacuum advance canister 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. Engine oil & filter should be changed before start-up.

CAMSHAFT & LIFTER RUN-IN
IMPORTANT: DO NOT ALLOW THE ENGINE TO RUN UNDER 2000 RPM FOR

THE FIRST 1/2 HOUR. Slow idle speeds may result in severe cam
and lifter wear.

START THE ENGINE AND BRING TO BREAK-IN RPM.
IMPORTANT NOTES AFFECTING YOUR WARRANTY
CAM LOBE WEAR—Cam lobe wear is almost non-existent unless mis-

matched parts are used or installation of the cam and lifters are
done improperly. Most cam damage is caused by the timing gear
loosening due to improper torque on bolt. Bolt holding gear to

IMPORTANT NOTE:
When using

Performer-Link True Rolling

timing chain and gear set (Cat.
#7800) 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 alignment. This requires indexing the
camshaft with a degree wheel to verify timing alignment. O.E.M. or non­Edelbrock timing gear sets are not recommended for use with Edelbrock
camshafts.

Figure 1— Timing Chain Sprocket Alignment

TIMING
MARKS

camshaft should be torqued carefully and a locking compound
applied to threads of bolts. Before installing your new Performer-Plus
camshaft, 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. This is especially true when
rebuilding your engine and a high-performance oil system is used,
which generates a heavier load on the camshaft gear system.
Edelbrock camshafts are designed to use O.E.M. type gears only.

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.
SPECIAL INSTRUCTIONS
IGNITION TIMING—Increased initial setting to 12-14 BTDC. Total of initial

and centrifugal advance not to exceed 340.
PLEASE NOTE: The best combination for any particular vehicle or appli-

cation must be determined by trial and error using the above infor-

mation as a guideline.
TUBULAR EXHAUST SYSTEM—For best performance, a tubular exhaust

system is recommended with the

Performer

package to provide the

most low-end torque.
