CAM LOBE DAMAGE: Cam lobe wear is almost non-existent unless
mismatched parts are used or installation of the cam and lifters is done
improperly. Cam damage can result from the timing gear loosening due
to improper torque on bolts. Bolts holding gear to camshaft should be
torqued carefully and a locking compound applied to threads of bolts.
Before installing your new hydraulic roller camshaft, check the gear drive
on the distributor and oil pump for any signs of wear. If worn, be sure to
replace with a new gear or you may wear out your camshaft prematurely.
High-pressure oil pumps are not recommended with hydraulic roller
camshafts. Edelbrock camshafts are designed for use with Edelbrock
timing chains.
In order for this Performer RPM roller cam to be covered under ANY
WARRANTY, you MUST use the correct Valve Springs. Failure to install the
correct valve springs may cause lifters not to follow the cam lobes and
damage engine parts. This camshaft is designed to function with valve
Springs that have a closed pressure of 110-120lbs, open pressure of
330-340 lbs and a lift of .550” (.600” for #2207). Special high
performance retainers may be necessary with your installation for proper
spring height. Do not use rotator type valve springs or retainers for this
NOTE: Edelbrock Sure Seat Valve Springs #5703 are
recommended for use with Performer camshafts #2208 &
#2209 ONLY. RPM camshafts must use appropriate springs
from another supplier.
PUSHRODS AND ROCKER ARMS: Edelbrock #9653 pushrods, and
high performance, roller 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 for correct lifter preload.
TIMING CHAIN: Use Edelbrock Performer-Plus Timing Set #7800 or
7802, Accu-Drive gear drive #7890, or Hex-A-Just Timing Set #7331
ONLY. Do not use late model timing chain and gear sets that are designed
for emission-controlled engines. OEM timing sets are machined in a
retarded position and are not recommended for this installation.
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 damaged. See Installation Instructions section for end play
OPERATING CLEARANCES: 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:
Improper valve-to-piston clearance (this should be no less than
Rocker arm stud slot clearance (both ends; valve closed and
NOTE: We recommend the use of roller rockers.
LIFTERS: Edelbrock offers retro-fit roller lifters for pre-1986 engines,
3. Proper spring settings (see dimensions with spring instruction
part #97383. Replacement OEM or Edelbrock #97384 lifters may be
sheet). Correct dimensions mean maximum performance and
used in 1987 and later engines. To install your roller lifters, use fresh
longer engine life.
clean oil on the lifter and the lifter bore just prior to installing. Make sure
to re-install the factory guide system (if equipped). The guide bar (high
side of tappet) must face the opposite side of block.
(Be sure to keep all parts in order)
IMPORTANT NOTICE: If the air conditioning condenser needs to be removed to provide clearance for camshaft removal, have the system
evacuated by an appropriate repair facility BEFORE starting the installation. The facility can recharge the system after installation.
Disconnect the battery.
Tag and remove vacuum lines.
Drain radiator coolant. Drain plug will normally be located on lower
right or left side of the radiator facing the engine.
Remove valve covers.
Remove radiator and air conditioning condenser if so equipped. In
some cases, the front grille may have to be removed. Measure
distance from front cover to grille or brackets that may interfere with
camshaft against the length of the camshaft.
Remove distributor cap and wires, rotate engine until rotor points
towards number 1 terminal in cap and pointer on front cover is on
top dead center (TDC) and remove distributor. (see Fig. 1)
Remove the gas cap to relieve pressure. Disconnect fuel line and
plug. Replace gas cap.
Disconnect all linkage from carburetor such as throttle, throttle
springs, transmission, cruise control and automatic choke.
Tag and remove coil wires and sensor wires.

13. Remove crankshaft pulley, and using a suitable puller, crankshaft
15. Remove fuel pump and fuel pump pushrod. Rotate engine until
timing marks are aligned as in Figure 2.
14. Loosen oil pan and remove water pump and front cover.
16. Remove bolts retaining camshaft sprocket. Remove sprocket and
chain. For 1987-later engines, remove camshaft thrust plate.
NOTE: The front cover oil seal should be replaced before the
front cover is re-installed.
17. Remove camshaft.
Check lifters as covered in Lifters section. Coat cam lobes with
fresh clean oil. Lube distributor drive of cam with assembly lube
Install new camshaft with factory thrust plate (if applicable), new
sprockets, and timing chain. Torque sprocket bolts to 25 ft/lbs.
NOTE: Roller cams require the use of a cam thrust button
spacer to control camshaft end play in pre-1987 engines.
Check camshaft end-play, maintain between .005" and .010".
This must be checked with the timing cover, thrust button
(supplied), and gasket in place, just as it would be after final
assembly without the roller lifters installed. Some applications
may require that the thrust button be ground down slightly to
achieve proper clearance. When using a sheet-metal timing
cover, a water pump with a cam-stop is recommended to
prevent timing cover flex. See Edelbrock catalog for
appropriate pumps. Cast covers will not require a cam-stop.
Engines using a thrust plate do not require the thrust button.
CAUTION: When using Edelbrock Timing Sets with an
Edelbrock cam, straight up timing alignment is achieved. If any
other timing gear set is used, it is necessary to check camshaft
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. Use locking
compound on bolt threads holding gear to cam. Torque to
factory recommendations specified in factory service manual.
Align camshaft with timing marks lined up as recommended by
factory specifications (See Figure 2).
Reinstall your roller lifters using fresh clean oil on the lifter and the
lifter bore just prior to installing. Make sure to reinstall the factory
guide system (1987-later only). Check to make sure all lifters fit
freely in lifter bores.
Install front cover. Torque front timing cover bolts to 6-7 ft. lbs.
NOTE: Install new seal between oil pan and front cover if old
seal is damaged after removal. Use RTV silicone sealant on
seal to ensure proper seal to pan.
Install front harmonic balancer and torque to 60 ft.-lbs.
Install fuel pump and pushrod.
Install water pump using new gaskets and torque to 30 ft.-lbs.

Install pushrods with lube on both ends, making sure the
pushrod tip hits the center of the lifter cup. Install rocker
arms, but do not install adjusting nuts. You are now ready
to start valve adjustment.
With #1 cylinder at TDC firing position (Both #1 lifters are
down in the lifter bores & cyl #6 are up), adjust exhaust
valves on cylinder numbers 1, 3, 4, 8 and intake valves on
cylinder numbers 1, 2, 5, 7 as follows: You need to set
rockers at zero lash. While tightening the rocker nut, spin
the pushrod, when you feel resistance, you are at zero lash.
Tighten rocker nut 3/4 to 1 turn beyond zero lash.
Turn engine one complete revolution so #6 cylinder is at TDC
firing position and adjust exhaust valves on cylinder
numbers 2, 5, 6, 7 and intake valves on cylinders 3, 4, 6, 8
in the same manner. The valves are now adjusted.
10. Install intake manifold using new intake gasket set and torque bolts
to factory specifications.
NOTE: This cam is a cast cam and requires a cast distributor drive
Turn the engine over in direction of rotation until the No. 1 intake
valve closes and continue until the pointer on the front cover is
approximately five degrees before top dead center (BTDC).
See Figure 1 for firing order.
Re-install the distributor with the rotor pointing towards No. 1
terminal in the cap, and with the distributor housing in its original
position. If distributor will not drop down all the way to the flange
on the manifold, it will be necessary to align the distributor shaft
with the oil pump drive. Slowly rotate the engine until the distributor
drops down against the manifold, then continue turning until two
complete revolutions are completed and the timing marks once
again come to five degrees BTDC.
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.
Replace valve covers, carburetor linkage and remaining vacuum and
electrical connections.
Engine oil and filter should be changed before start-up.

IMPORTANT: Standard camshaft run-in is not required when using
a roller camshaft.
With the Edelbrock manifold and camshaft package installation, a
carburetor jet change and ignition timing changes may be required for
best performance. Due to the varied applications of years and models of
vehicles, no one combination could suffice for all installations. The
following procedure is only a guideline.
Increase initial setting to 14° BTDC (Before Top Dead Center). Total
advance not to exceed 38°. To select the proper distributor vacuum
advance port on your carburetor, we suggest the following procedure.
Before removing the vacuum line from your carburetor, with the engine
idling, pull the hose off the port that routes to the vacuum advance
canister. After the hose has been removed from the carb, place your
finger over the vacuum outlet. If (at idle), you feel your finger being
sucked in toward the carburetor, you have full-time vacuum advance. If
you do not feel any vacuum pulling at your finger with the engine at an
idle, you have timed/ported vacuum advance.
For best performance, a tubular exhaust system is recommended with
the Performer package to provide the most low-end torque. Please
consult your Edelbrock dealer or the Edelbrock catalog for a listing of
available Edelbrock Tubular Exhaust Systems.
