Easy Start HP103 camshaft kit

Allows easy starting by initially reducing compression; once started, the decompression cam retracts by centrifugal force and the engine runs normally, with no loss of performance
Designed as bolt-in camshafts for 103" engines with original compression ratio from 9.7:1 up to 10.5:1
Power in the high rpm range, 3,000 rpm - 6,000 rpm
Includes camshafts, gear cover gasket, bearings, retaining ring, O-ring, threadlocker and instructions.
Manufactured in the USA
The installer must check the spring limit, valve clearance and valve-to-piston clearance.
Works well with unmodified original heads and is ideal for S&S CNC ported heads.
Not suitable for models with OEM decompressors.
