Allstar Performance ALL90000 - Manual

1. Allstar gear drive for small block Chevrolet V8’s is the ultimate in precise cam timing. Heat treated
and case hardened gears eliminate timing chain stretch and harmonics. Camshaft and ignition timing
remain accurate at all engine speeds – and that means more horsepower!
2. Cam timing is infinitely adjustable to allow maximum performance from any profile. Camshaft for-
ward and rearward movements are controlled with needle bearing thrust washers.
3. Gear drive fits under most 2 pc. timing chain covers and the cam and cam gear can be removed
for inspection without dropping the oil pan. Allstar gear drives deliver maximum performance and reli-
ability.
