CAMSHAFT: Edelbrock Performer-Plus camshafts are ground specifically for use with the corresponding Performer manifold. The Performer
manifold #2171 or #3771, and Performer-Plus camshaft #2172, 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.
NOTE: Maximum performance is achieved when packages are used with a 4-bbl carburetor and headers, however packages may be used with
any of the following equipment:
➤ manifold/camshaft package only ➤ aftermarket carburetor specified in instructions and catalog
➤ 1-5/8" 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 RE-INSTALLATION, 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 your dealer immediately).

CAUTION: WARNINGS ABOUT YOUR WARRANTY
In order for this Performer-Plus cam and lifter kit to be covered
under ANY WARRANTY you MUST use the correct Edelbrock Sure
Seat Valve Springs or original equipment springs. Failure to install
new Edelbrock valve springs or original specification springs with
your new Performer-Plus 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 #5872 (standard) or #5972 (for use with valve rotators). Do not use dual valve springs with this camshaft.
2. Check and set spring height to factory specifications for your year
and model. If using Edelbrock #5872, set both intake and exhaust
to 1.820"; for #5972, set exhaust to 1.680".
various settings through the years, we advise checking service
manual for correct spring height setting for your vehicle.
3. You may use stock retainers and/or valve rotators with Edelbrock
valve springs, or for non-rotator engines, you may install
Edelbrock Valve Spring Retainers #9724 with stock valve locks.
LIFTERS
1. New lifters mustbe used with new camshaft. Use only the lifters
supplied with this kit.
2. Check to be sure that all lifters fit freely in the lifter bores and that
lifter bores were not machined for oversized lifters.
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 #7821. Do not use late model timing chain and
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 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
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 pushrod and adjusting nut on intake
rocker arm and adjust to zero clearance between rocker arm and
valve tip. For engines with non-adjustable rocker arms, continue to
tighten the adjusting nut until it bottoms out. If this adjustment is
less than one-half turn, you will need to purchase 0.060" longer
pushrods from your Ford dealer.
NOTE: Due to the
2. Turn the engine over again until the intake lifter just stops coming
down. At this point install pushrod and adjusting nut on exhaust
rocker arm and repeat the same procedure as above.
3. The above procedure assures correct hydraulic lifter pre-load.
Repeat this procedure for each of the other seven cylinders. For
non-adjustable rockers, torque rocker arm nuts to 20-25 ft./lbs.
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 & torque to factory spec. (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 prematurely wear out your
camshaft. Edelbrock camshafts are designed to use OEM-type
gears and oil pumps only. Do not use high volume, high pressure oil
pumps.
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-install radiator, fan shroud, and belts (if removed), 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 initial break-in.
under 2000 rpm for the 1/2 hour. Vary engine speed between
2000 & 2500 rpm. Slow idle speeds will result in severe cam &
lifter wear.
1. Start the engine and bring to break-in rpm.
IMPORTANT INSTRUCTIONS
AFFECTING YOUR WARRANTY
Do not allow the engine to run
☞ 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-Plus Timing Chain and Gear
Set #7821. 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

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.
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
0.100").
2. Rocker arm stud slot clearance (both ends; valve closed and open).
3. Proper valve spring installed height settings (1.820" intake and
exhaust for Edelbrock Sure Seat springs #5872; 1.820" intake and
1.680" exhaust for Edelbrock Sure Seat springs #5972)
.
SPECIAL INSTRUCTION:
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). 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.). Refer to the Edelbrock Performer Series carburetor
Owner's Manual for calibration procedures. 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, re-connect the vacuum advance line.
NOTE: The best combination for any particular vehicle or applica-
tion 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 24° to 28° maximum advance at 10-11 inches of
vacuum and 6° to 8° advance at 3-4 inches of vacuum.
HEADERS:
For best performance, headers are recommended with the
Performer package. For this application, they should be 1-5/8"
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 backpressure mufflers.
NOTE: The best combination for any particular vehicle or applica-
tion must be determined by trial and error using the above information as a guideline.
Use of a straight
edge to help align
the two timing
marks is highly
recommended
