12. Disconnect fuel pump outlet line from fuel pump; remove fuel pump.
Remove front cover bolts and cut oil pan gasket flush with cylinder
block. Remove front cover and water pump as an assembly.
NOTE: The front cover oil seal should be replaced before the front
cover is re-installed.
13. Rotate engine until timing marks are aligned as shown in
Figure 1.
14. Remove cam sprocket bolt, washer, and fuel pump eccentric. Slide
sprocket and timing chain forward to remove.
15. Remove thrust plate and camshaft. Using appropriate gear puller,
remove crank sprocket.
• VALVE SPRINGS
CAUTION: WARNINGS 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 springs. Failure to install new
Edelbrock valve springs or original specification springs 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 #5882 (standard) or #5982 (for valve rotators) or OE valve
springs. Do not use dual valve springs with this camshaft.
2. Check and set spring height to factory specifications for your year and
model. If using Edelbrock #5882, set to 1.780"; for #5982, set
exhausts to 1.600". NOTE: Due to the various settings through the
years, we advise checking Mitchell, Motors, Chilton, or Ford service
manuals for correct spring height setting for your vehicle.
3. For non-rotator engines, you may want to install Edelbrock Valve
Spring Retainer Kit #9724 and Valve Stem Locks #9611.
NOTE: #9611 fit single groove valve stems only; not for use with
multi-groove valves.
• LIFTERS
1. New lifters must be used with new camshaft. Use only the lifters
supplied with this kit.
2. Check to be sure that all lifters fit freely in the lifter bores.
• INSTALLATION INSTRUCTIONS
1. Coat cam lobes and bottom of each lifter with MoS2 lube (supplied)
to prevent cam lobe and lifter wear from occurring during initial startup.
2. Install new camshaft with new sprockets, timing chain and lifters.
CAUTION: Use Edelbrock Performer-Plus True Rolling Timing Chain
and Gear Set #7811 (1973-95) or #7820 (1965–72-1/2).
Do not use late model timing chain & gear sets that are designed in
a retarded position and are not recommended for this camshaft
installation. Edelbrock Timing Sets feature three keyways for
specific timing selection. Use locking compound material on the
bolt threads holding timing gear to cam. Torque to factory
recommendations specified in motor repair manual. Install
camshaft with timing marks lined up as recommended by factory
specifications.
See Figure 1.
When using Performer-Plus Timing Chain and Gear Sets (7800
series) 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 pre-load.
• VALVE ADJUSTMENT
1. Turn the engine over
until the No. 1 cylinder
exhaust lifter starts to
move up. At this point
install pushrod and
adjusting nut on intake
rocker arm and adjust to
zero clearance between
rocker arm and valve tip.
For engines equipped
with adjustable rocker
arms, continue
tightening the adjusting
nut one-half (1/2) turn.
Check to make sure that
the slot in the rocker arm
has clearance at the stud
in the full open and
closed positions. If there
is no clearance in the
closed position a 0.060"
longer pushrod is
required. For engines with non-adjustable rocker arms, continue to
tighten the adjusting nut until it bottoms out. If this adjustment is less
than one-half turn, you will need to purchase the 0.060" longer
pushrods from your Ford dealer.
2. Turn the engine over again until the intake lifter just stops coming
down. At this point install pushrod and adjusting nut on exhaust
rocker arm and repeat the same procedure as above.
3. The above procedure assures correct hydraulic lifter pre-load.
Repeat this procedure for each of the other seven cylinders. For nonadjustable rockers only, torque rocker arm nuts to
20-25 ft./lbs.
4. Re-install front cover, fuel pump, water pump, and oil pan using new
gaskets.
5. Install intake manifold using new intake gasket set and torque
manifold bolts to 25 ft./lbs.
6. Install crankshaft dampener and torque to factory specification.
• 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.
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 OEM-type gears and oil
pumps 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 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. Re-install air conditioner, if so equipped.
6. Re-install radiator, fan shroud, and belts (if removed), fill radiator with
coolant and re-connect battery.
7. Double check all connections, fuel lines, etc. before starting engine.
