MODEL: 262-400 c.i.d. Chevrolet V8, 1957 & 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 #7101, and Performer RPM camshaft #7102, 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 high performance cylinder heads 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
• 1-3/4" headers
• fuel delivery system of sufficient capacity
• 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 #5703. 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.
NOTE: Drive pin in front of cam should be pressed into the
timing gear from the rear of the gear (camshaft side) until the
pin protrudes from the front of the gear by .060”. This will
allow the pin to engage a drive hole in the one-piece fuel pump
eccentric. A replacement fuel pump eccentric can be ordered
from your Ford dealer if necessary- order part number C3AZ6287-A.
CAUTION: Use Edelbrock Performer-Plus True Rolling
Timing Chain and Gear Set #7800 or Accu-Drive gear drive set
#7890. 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 2.
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 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 1/2 hour. Slow idle speeds
may result in severe cam and lifter wear. 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.
• CAUTION: Use Edelbrock Performer-Link Timing Chain and Gear Set #7800 or Accu-Drive gear drive #7890. Do not use late
model timing chain and gear sets that are designed for emission-controlled engines. These timing sets are machined in a retardedposition and are not recommended for this camshaft installation. Edelbrock Timing Sets feature three keyways for specifictiming selection.
• 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
CAUTION: Some models of early vehicles use a short pin in the camshaft. For these vehicles, we suggest grinding the long pin in
the Edlebrock cam to the same length as the short pin, or remove the stock pin and install it with the Edlebrock cam.
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.
• CARBURETION AND IGNITION TIMING
Best carburetor results were with the Edelbrock Performer Series carburetors # 1405 (600 cfm with manual choke), #1406 ( 600 cfm
with electric choke), or #1407 (750 cfm with manual choke). Stock jetting can be used for most installations, however, various conditions may require re-calibration for optimum performance (changes in altitude, temperature, exhaust system, etc.). 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 36 degrees with initial and centrifugal weights
combined and should be at full advance at 3000-3500 rpm. After timing is adjusted, re-connect 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.
• VACUUM ADVANCE
For best cruise and light throttle response, a vacuum advance
curve was used with 16° to 20° maximum advance at 14-16
inches of vacuum and 4° to 10° advance at 10-12 inches of
vacuum.
• 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.
