MODEL: 389-455 c.i.d. Pontiac V8, 1965 & later
• PLEASE study these instructions carefully before installing your new camshaft. If you have any questions or problems, do not hesitate to call our Technical Hotline at: 1-800-416-8628.
• CAMSHAFT: Edelbrock Performer RPM camshafts are ground specifically for use with the corresponding Performer RPM manifold. The Performer RPM manifold #7156, and Performer RPM camshaft #7157, are designed to work as a team to give you better
driveability and performance. They are dyno-matched and street-proven. For best results, use the Edelbrock manifold/camshaft package with the carburetor and headers we recommend. The Performer RPM camshafts are designed for use with modified or RPM
cylinder heads, #6057-59 and valve train components only. Screw-in studs and H.P. adjustable rocker arms must be used.
NOTE: Maximum performance is achieved only when the Edelbrock Performer RPM Power Package components are used with the
following equipment:
•
Performer RPM manifold/camshaft/timing set/valve springs
•
Performer Series carburetor #1407
•
fuel delivery system of sufficient capacity
•
1-3/4" headers
•
aftermarket/re-curved distributors
• IMPORTANT: This instruction sheet provides general installation guidelines which can affect your warranty. Read it carefully. It is
not our intent to cover each detail of installation here; a step-by-step procedure manual would be far too lengthy. We want to caution
you that installing a camshaft is a complicated procedure that requires a good general knowledge of automotive engines. If you are
not confident that you can complete the camshaft installation successfully, we suggest you consider having it installed by an experienced mechanic.
CAUTION: Improper installation will result in LOW MILEAGE, POOR PERFORMANCE, COSTLY REINSTALLATION,
and ENGINE DAMAGE.
TO AVOID THESE PROBLEMS YOU MUST DO THE FOLLOWING:
Carefully study and understand all instructions.
Examine the camshaft for possible shipping damage (if damaged contact you dealer immediately).

• 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 or equivalent. Failure to
install new Edelbrock valve springs or equivalent 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 #5757. 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.
• 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-Plus True Rolling
Timing Chain and Gear Set #7812. 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 tim-
ing 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 2.
When using Performer-Plus Timing Chain and Gear Sets (7812
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 recommended for this installation.
After the cam is installed and timed correctly (see Figure 2), it
will be necessary to check each pushrod for correct lifter preload.
• 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 preload.
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 60 ft./lbs.
• 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. Refill 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 initial break-in. Do not allow the engine to run
under 2000 rpm for the first hour. Vary engine speed between
2000 and 3000 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 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 clipped.
When installing a camshaft, it is always important to check for
proper operating clearances, especially when high performance
components are used. Things to look for that can cause failure
and damaged parts are as follows:
1. Improper valve-to-piston clearance (this should be no less than
0.080").
2. Rocker arm stud slot clearance (both ends; valve closed and
open).
3. Proper spring settings (see dimensions with spring instruction
sheet; correct dimensions mean maximum performance and
longer engine life).
• SPECIAL INSTRUCTIONS
With the Edelbrock manifold and camshaft package plus a
header installation, a carburetor jet change may be required for
best performance. Due to the varied applications of year and
model of vehicles, no one combination could suffice for all
installations. The following procedure is only a guideline and
in many cases, the manufacturing specifications for recommended carburetors or timing may be best.
• IGNITION TIMING
Ignition timing for this package may vary with each application. A good starting figure would be between 10 degrees to 14
degrees initial timing at idle with vacuum advance disconnected. Total advance should not exceed 32 degrees to 34 degrees
with initial and centrifugal weights combined and should be at
full advance at 3000-3500 rpm. After timing is adjusted, reconnect the vacuum advance line. NOTE: The best combination for any particular vehicle or application must be determined by trial and error using the above information as a
guideline.
• HEADERS
For best performance, headers are recommended. For this
application, they should be 1-3/4" diameter, approximately 31"
long and terminating into a 3" collector. The remainder of the
exhaust system should consist of dual exhaust and tail pipes, at
least 2" diameter with low back-pressure mufflers.
• WARNING
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. The end flap or label from
your Sure Seat Valve Spring box must be sent in with your
camshaft warranty card.
Failure to install new Edelbrock Sure Seat Valve Springs with
your new Performer RPM cam and lifter kit could cause the
cam lobes to wear excessively and could cause additional
engine damage. IF YOU HAVE ANY QUESTIONS ABOUT
THIS APPLICATION, PLEASE CONTACT OUR TECHNICAL DEPARTMENT IMMEDIATELY.
• CAUTION: Use Edelbrock Performer-Link Timing Chain and Gear Set #7812. Do not use late model timing chain and gear sets that
are designed for emission-controlled engines. These timing sets are machined in a retarded position and are not recommended for this
camshaft installation. Edelbrock Timing Sets feature three keyways for specific timing selection.
• PLEASE complete and mail your warranty card. Be sure to write the model number of this product in the “Part #____” space.
• THANK YOU.
