• CAUTION:
Use Edelbrock Performer-Link Timing Chain and Gear
Set #7820 or Accu-Drive gear drive #7892. 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

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 perfor-
mance. 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, 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.
• HEADERS
For best performance, headers are recommended. For this application,
they should be 1-5/8" or 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.
