•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.
2. Install new camshaft with new sprockets, timing chain and lifters.
CAUTION:
Use Edelbrock Performer-Link True Rolling Timing
Chain and Gear Set #7820 or Accu-Drive gear drive set #7892. 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 selec-
tion. Use locking compound material on the bolt threads holding tim-
ing gear to cam. Torque to factory recommendations specified in motor
repair manual. Install camshaft with timing marks lined up as recom-
mended 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
High performance pushrods and rocker arms and studs are recommend-
ed for this installation.
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 adjusting nut on intake rocker arm and
adjust to zero clearance between rocker arm and valve tip. From this
point turn adjusting nut down (clockwise) 1/4 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 tip. From this
point turn adjusting nut down (clockwise) 1/4 turn more for final
adjustment.
3. The above procedure assures correct hydraulic lifter pre-load. Repeat
this procedure for each of the other seven cylinders.
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. (except for end bolts of early style heads which have
no support; hand tighten only).
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 RPM cam and lifter kit to be covered under
ANY WARRANTY you MUST use the correct Edelbrock Sure Seat
Valve Springs. Failure to install new Edelbrock valve springs with your
new Performer RPM cam could cause the cam lobes to wear excessive-
ly and could cause additional engine damage.
1. This camshaft is designed to function with Edelbrock Sure Seat valve
springs #5722. Do not use dual valve springs with this camshaft. Valve
Spring Retainers #9733 may be used if your heads are equipped with
Chevrolet valves. Retainers #9724 will give 0.100" taller installed
height and may be necessary for proper spring height if you are using
OE specification Ford valves. Do not use rotator type valve springs or
retainers for this application.
• LIFTERS
1. New lifters must be used with new camshaft. Use only the high rev
lifters supplied with this kit.
2. Check to be sure that all lifters fit freely in the lifter bores and that the
factory did not install oversized lifters in your block to compensate for
machining errors.
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 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 approx-
imately 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 posi-
tion.
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-fill 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 the initial break-in.
Do not allow the engine to run under 2000
rpm for the first 1/2 hour.
Vary engine speed between 2000 and 2500
rpm. Slow idle speeds may result in severe cam and lifter wear.
1. 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
