15. Rotate engine until timing marks are aligned as in Figure 1.
16. Remove bolts retaining camshaft sprocket. Remove sprocket and
chain.
17. Remove crank sprocket using a gear puller.
18. 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 orig-
inal 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 #5862.
2. For older vehicles and vehicles with high mileage we highly recom-
mend replacing the valve springs with Sure Seat Valve Springs #
5862.
3. Check spring height and set to factory specifications for correct year
and model (1.77"-1.83" for original springs with valve rotators; 1.88"
for Edelbrock #5862 without rotators).
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 INSTRUCTIONS
1. Coat cam lobes and bottom 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 camshaft with timing marks lined up as recommended by fac-
tory specifications. See Figure 2.
CAUTION: When using Performer-Link True Rolling Timing Chain and Gear
Set #7810 with an Edelbrock cam and lifter kit, straight up timing
alignment is achieved. If any other timing gear set is used, it is neces-
sary 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 non-Edelbrock timing gear sets are not recom-
mended for use with Edelbrock camshafts. Use locking compound
material on bolt threads holding gear to cam. Torque to factory rec-
ommendations (20 ft./lbs.).
3. Install new camshaft with new sprockets and timing chain.
PUSHROD AND ROCKER ARM INSTALLATION—After the cam is installed
and timed correctly (see Figure 2), install pushrods, lifters and rocker
arms. Replace any worn or damaged rocker arms.
VALVE ADJUSTMENT
1. Rotate engine until timing marks are aligned and #1 cylinder is at Top
Dead Center (TDC). Back off rocker arm adjusting nut on #1 intake
and exhaust rocker arms until play in pushrod is detected.
2. Tighten rocker arm nut until play in pushrod is eliminated, then tight-
en adjusting nut 1/2 additional turn. With engine at #1 firing position,
adjust intake valves 1,2,5, and 7 and exhaust valves 1,3,4, and 8.
3. Rotate engine 1 complete turn (360 Þ) to #6 firing position and follow
the same procedure for adjusting valves. With engine at #6 TDC,
adjust intake valves 3,4,6 and 8 and exhaust valves 2,5,6 and 7.
NOTE: On computer-controlled engines, adjusting the lifter pre-load any
looser than specified may cause valve clatter which will activate the
knock detector and result in retarded ignition timing.
4. Install front timing cover with new gasket.
NOTE: Install new seal between oil pan and front cover if old seal is
damaged after removal. Use RTV silicone sealant 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 85 ft./lbs.
7. Install water pump using new gaskets and torque to 30 ft./lbs.
8. Install intake manifold using new intake gasket set and torque bolts to
25 ft/lbs. NOTE: Before installing intake manifold, you may want to
change the oil filter and pour the new motor oil into the lifter valley
over the new cam and lifters. This will aid lubrication upon initial
engine start-up.
DISTRIBUTOR INSTALLATION AND ENGINE TIMING
1. Turn the engine over in direction of rotation until the #1 intake valve
closes and continue until the pointer on the front cover is approxi-
mately five degrees before top dead center (BTDC). If valve cover is
already on engine, you may remove #1 spark plug and slowly rotate
engine until you can feel compression with your finger, then continue
until the pointer on the front cover is approximately five degrees
BTDC. See Figure 1 for firing order.
2. Re-install the distributor with the rotor pointing towards No. 1 termi-
nal in the cap, and with the distributor housing in its original position.
If distributor will not drop down all the way to the flange on the mani-
fold, it will be necessary to align the distributor shaft with the oil
pump drive. Slowly rotate the engine until the distributor drops down
against the manifold, then continue turning until the rotor is pointing
towards #1 terminal and the timing marks once again come to five
degrees BTDC.
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, throttle linkage and remaining vacuum and
electrical connections.
5. Engine oil & filter should be changed before start-up and again after
camshaft break-in.
CAMSHAFT & LIFTER RUN-IN
IMPORTANT:DO NOT ALLOW THE ENGINE TO RUN UNDER 2500 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 AS SOON AS POS-
SIBLE.
NOTE: Check all fuel lines and water hoses for leakage before trying to
start engine.
IMPORTANT NOTES 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 are
done improperly. Most cam damage is caused by the timing gear
loosening due to improper torque on bolts. Bolts holding gear to
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 a new gear or you may
wear out your camshaft prematurely. High-volume oil pumps are not
recommended with Performer-Plus camshafts. Edelbrock camshafts
are designed to use O.E.M. type gears only.
