14. Loosen oil pan and remove water pump and front cover.
NOTE: The front cover oil seal should be replaced before the front
cover is re-installed.
15. Remove fuel pump and fuel pump pushrod. Rotate engine until tim-
ing 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 to remove sprocket.
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 original equipment valve
springs. Failure to do so could cause the cam lobes to wear exces-
sively 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 #5802 (std. retainer set),
or for rotators, use #5902.
2. For older vehicles and vehicles with high mileage we highly recom-
mend replacing the valve springs with Sure Seat Valve Springs #
5802 (std. retainer set), or for use with valve rotators, #5902.
NOTE: Sure Seat Springs #5902 not applicable to cylinder heads
1977 and later with casting #14014416. These heads must use
Edelbrock spring set #5802.
3. Check spring height and set to factory specifications for correct year
and model. DUE TO THE MANY POSSIBLE SETTINGS OVER THE
YEARS, WE ADVISE CHECKING MOTORS, CHILTON, OR FACTORY SER-
VICE 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 new camshaft with new sprockets and timing chain.
CAUTION: When using Performer-Link True Rolling Timing Chain and
Gear Set #7800/#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. 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. Use locking
compound material on bolt threads holding gear to cam. Torque to
factory recommendations specified in Motors or other repair manual.
3. Install camshaft with timing marks lined up as recommended by fac-
tory specifications. See Figure 2.
• PUSHROD AND ROCKER ARM INSTALLATION
After the cam is installed and timed correctly (see Figure 2), install
pushrods, 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
adjust to zero clearance between 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
point turn adjusting 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 seven cylinders.
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 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 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 posi-
tion. If distributor will not drop down all the way to the flange on the
manifold, 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 two complete
revolutions are completed 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, carburetor linkage and remaining vacuum and
electrical connections.
5. Engine oil and 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 2000
RPM FOR THE FIRST 1/2 HOUR. Slow idle speeds may result in
severe cam and lifter wear. Vary engine speed between 2000 and
2500 rpm.
START THE ENGINE AND BRING TO BREAK-IN RPM.
