DUE TO THE MANY POSSIBLE SETTINGS OVER THE YEARS, WE
ADVISE CHECKING MOTORS, CHILTON, OR FACTORY SERVICE MANU-
ALS 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 OCCUR-
RING 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 manu-
al.
4. Install camshaft with timing marks lined up as recommended by fac-
tory 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 rock-
er 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 termi-
nal 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

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.
TIMING
MARKS
Figure 1— Timing Chain Sprocket Alignment
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 non-
Edelbrock timing gear sets are not recommended for use with Edelbrock
camshafts.
