INSTRUCTIONS
• 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-Plus camshafts are ground specifically for use with the corresponding Performer manifold on engines operat-
ing between idle and 5500 rpm. The Performer 5.0 EFI manifold #3821 and Performer-Plus hydraulic roller lifter camshaft #3722 are designed to
work as a team to give you better driveability and street performance. They are dyno-matched and street-proven. For best results, use the
Edelbrock manifold/camshaft package with the Throttle Body/EGR Plate and headers we recommend. The Performer-Plus hydraulic roller lifter
camshafts are designed for use with stock or Edelbrock Performer aluminum cylinder heads. Edelbrock Performer-Plus cam #3722 is street legal
in all 50 states, E.O. #D-215-14.
NOTE: Maximum performance is achieved only when the Edelbrock Performer 5.0 EFI Power Package components are used with the following
equipment:
• Performer 5.0 EFI manifold/camshaft/timing set/valve springs
• Edelbrock/BBK 70mm Throttle Body #3825 and EGR Plate #3828
• Tubular Exhaust System #6845 or #7945 (1986-93 Mustangs only)
• Edelbrock RPM Series Cat-back Exhaust System #5645 (1987-93 Mustang GT) or #5646 (1986 Mustang GT and 1986-93
Mustang LX)
• 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 com-
plete 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 your dealer immediately).

• For ease of installation, keep all parts in some sort of order.
WARNING: Do not remove radiator cap or radiator hose if engine is
hot.
1. Disconnect negative battery cable and drain cooling system.
2. Disconnect necessary electrical connections, control cables, link-
ages, vacuum hoses, ventilation hoses, and coolant hoses at throttle
body and manifold. Do not disconnect fuel lines unless
absolutely necessary. Special tooling and procedures are
required to re-install fuel lines. See "Fuel Line Removal and
Installation" Figure 3, page 4.
3. Remove distributor cap and spark plug wires as an assembly. Place
reference mark on distributor for rotor alignment during reassembly.
Remove retaining bolt and distributor.
4. Remove cover plates, retaining bolts, upper intake manifold and gas-
ket. Remove accessory brackets attached to lower manifold. Remove
heater tube assembly from lower manifold. Remove retaining bolts,
lower manifold, gaskets, and seals.
5. Remove fuel pump.
6. Remove rocker arms and pushrods.
7. Remove old valve lifters.
8. Remove crankshaft pulley and, using a suitable puller, crankshaft
dampener.
9. Loosen oil pan and remove front cover.
NOTE: The front cover oil seal should be replaced before the front
cover is re-installed.
10. Rotate engine until timing marks are aligned as shown in Figure 2.
11. Remove cam sprocket bolts. Slide sprocket and timing chain forward
to remove.
12. Remove camshaft. Using appropriate gear puller, remove crank
sprocket.
• VALVE SPRINGS
CAUTION: WARNINGS ABOUT YOUR WARRANTY
In order for this Performer-Plus cam to be covered under ANY WAR-
RANTY you MUST use the correct Edelbrock Sure Seat Valve Springs
or equivalent. Failure to install new Edelbrock valve springs or equiv-
alent 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 #5822 or #5922 (for rotators). Do not use dual valve springs
with this camshaft.
• LIFTERS
1. The original hydraulic roller lifters should be used with this
camshaft. Inspect each lifter for unusual wear and replace as need-
ed with new original equipment Ford or SVO lifters.
2. Check to be sure that all lifters fit freely in the lifter bores.
• INSTALLATION INSTRUCTIONS
1. Coat cam lobes and rollers 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 Street Legal Performer-Plus True Rolling
Timing Chain and Gear Set #7814. 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 Street
Legal Timing Sets feature a single keyway for accurate timing selec-
tion. Use locking compound material on the bolt threads holding tim-
ing gear to cam. Torque to 35 ft./lbs. or factory recommendations.
Install camshaft with timing marks lined up as recommended by fac-
tory specifications. See Figure 2.
When using Performer-Plus Timing Chain Sets (#7814 or #7811)
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 align-
ment. O.E.M. or non-Edelbrock timing gear sets are not recommend-
ed for use with Edelbrock camshafts.
• INSTALLING PUSHRODS AND ROCKER ARMS
After the cam is installed and timed correctly (see Figure 2), it will be
necessary to check each pushrod for correct lifter pre-load. Before
installation, be sure to coat friction surfaces of pushrods, rocker
arms and pivots with a suitable lubricant such as motor oil or
assembly lube.
• VALVE ADJUSTMENT
1. Turn the engine over until the No. 1 cylinder is at Top Dead Center
(TDC) on the compression stroke (both lifters will be at the bottom of
their travel in the lifter bores). Install both intake and exhaust
pushrods, rocker arms, rocker arm pivot, and rocker arm bolts.
Carefully tighten bolts while feeling pushrods for vertical clearance.
As soon as all vertical clearance is gone from pushrods, count num-
ber of turns until bolts bottom out. There should be 1/2 to 1 full turn
of lifter pre-load. If vertical clearance exists after bolts bottom out,
longer-than-stock pushrods are required. They are available from
Ford dealers or other pushrod suppliers. If excessive lifter pre-load
exists, use shims under rocker arm pivots to achieve 1/2 to 1 turn
pre-load.
2. The above procedure assures correct lifter pre-load. Repeat this pro-
cedure for each of the other seven cylinders by rotating the engine
90° and following the firing order (1-3-7-2-6-5-4-8).
3. Re-install front cover, fuel pump, water pump, and oil pan using new
gaskets.
4. Install intake manifold using new intake gasket set and torque mani-
fold bolts to 25 ft./lbs.
5. Install crankshaft dampener and torque to 70-90 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 per-
formance 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 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. 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.
1. No break-in is required with roller lifters.
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 chipped.
When installing a camshaft, it is always important to check for prop-
er operating clearances, especially when high performance compo-
nents are used. Things to look for that can cause failure and dam-
aged 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).
• IGNITION TIMING
Ignition timing for this package may vary with each application. Best
results were obtained using stock Ford timing setting specified for
your year and model vehicle (10° BTDC initial). NOTE: The best com-
bination 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. Edelbrock Tubular
Exhaust System #6845 or #7945 is a street legal replacement part
for 1986-93 Mustangs with the 5.0L V8. RPM Series Cat-back
Exhaust systems are also available featuring mandrel-bent tubing
and free-flowing RPM Series stainless steel mufflers. Use Edelbrock
RPM Series Cat-back Exhaust System #5645 (1987-93 Mustang GT)
or #5646 (1986 Mustang GT and 1986-93 Mustang LX).
• WARNING
In order for this Performer-Plus cam to be covered under ANY WAR-
RANTY you MUST use the correct Edelbrock Sure Seat Valve Springs
or original equipment replacements. The end flap or label from your
Sure Seat Valve Spring box must be sent in with your camshaft war-
ranty card.
Failure to install new Edelbrock Sure Seat Valve Springs with your
new Performer-Plus cam could cause the cam lobes to wear exces-
sively and could cause additional engine damage. IF YOU HAVE ANY
QUESTIONS ABOUT THIS APPLICATION, PLEASE CONTACT OUR
TECHNICAL DEPARTMENT IMMEDIATELY.
