Thank you for choosing COMP Cams® products; we are proud to be your manufacturer of choice. Please read
this instruction sheet carefully before beginning installation, and also take a moment to review the included
limited warranty information.
COMP Cams® belt drives represent the ultimate in cam timing systems. Our belt drives are designed to absorb a
significant amount of crankshaft harmonics, which will affect valve motion if they reach the valve train. COMP
Cams® belt drives require less power to operate than conventional belt drives. Last but not least, our belt drives
have proven to be more durable than either gear or chain drives.
Excellent for all NASCAR and NHRA applications
Unique camshaft thrust adjustment system does not require the use of shims to set end play
Belt idler reduces belt “flap”
High performance belt
Idlers available in different diameters for align bored blocks
Adjustable camshaft timing with simple Vernier sprocket
Double lip oil seals ensure maximum crankcase vacuum
Installation Instructions:
NOTE: The COMP Cams® Chevrolet belt drive system can be installed on an assembled engine.
However, the installing mechanic should be prepared to remove the camshaft for the purpose of
drive hub installation and end play adjustment.
