IMPORTANT NOTES 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 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 Performer-Plus 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 prema-
turely. High-volume oil pumps are not recommended with Performer-
Plus camshafts. Edelbrock camshafts are designed to use O.E.M.
type gears only.
• 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.
• TUBULAR EXHAUST SYSTEM
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. Be sure to
check local emission control regulations for legality of camshaft and
exhaust system changes.

• LUBRICATION:
Use Edelbrock Break-In Oil or Edelbrock Zinc Oil Additive in combina-
tion with your regular oil to give your engine maximum protection
during the break-in period. Once break-in has been completed,
drain the oil and replace it with Edelbrock High Performance Motor
Oil for the best in anti-friction wear protection.
• IMPORTANT NOTE:
When using Performer-Link timing chain and gear set (#7800 or
#7802) with an Edelbrock cam and lifter kit, straight up timing align-
ment 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 recom-
mended for use with Edelbrock camshafts.
• SPECIAL NOTICE:
Edelbrock Performer-Plus camshaft/lifters/lube kit #3702 has
received E.O. #D-215-19 making them legal for street use on pollu-
tion-controlled motor vehicles in all 50 states. To assist you with
emissions equipment certification, we have included a fan shroud
decal to help testing personnel verify that the camshaft is a legal
replacement part for small-block Chevrolet/GMC vehicles. The adhe-
sive-backed decal should be affixed to your fan shroud next to the
existing emission and engine specification decal. Do not cover your
original equipment specification decal with the Edelbrock Performer-
Plus camshaft decal.
