8. Remove carburetor and intake manifold. Remove fuel pump.
9. Remove rocker arms and pushrods.
CAUTION: If your engine has non-adjustable rocker arms
(1969-
1/2 or later), you must install screw-in studs and high per-
formance adjustable rocker arms. Crane and other manufacturers
sell conversion kits for this which do not require removal and
machining of the heads.
10. Remove hydraulic valve lifters.
11. Remove crankshaft pulley and, using a suitable puller, crank-
shaft dampener.
12. Loosen oil pan and remove front cover.
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 excessively 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. Special H.P. retainers may be necessary with your
installation for proper spring height. 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.
• INSTALLATION INSTRUCTIONS
1. Coat cam lobes and bottoms of each lifter with MoS2 lube (sup-
plied) 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-Plus True Rolling
Timing Chain and Gear Set #7811/#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 recommend-
ed for this camshaft installation. Edelbrock Timing Sets feature
three keyways for specific timing selection. Use locking com-
pound 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 veri-
fy 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 rec-
ommended 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 com-
ing 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.
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 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-fill radiator with coolant and re-connect battery.
7. Double check all connections, fuel lines, etc. before starting
engine.
