Cloyes Timing Set SB Chev Roller #CY9-3100A

With Cloyes Hex-A-Just timing sets, infinitely adjustable cam timing is as simple as turning an Allen wrench. Consisting of SAE 1144 billet steel cam and crank sprockets and a true roller timing chain, Cloyes Hex-A-Just timing sets use a special hex-head bushing installed on your cam's dowel pin. This bushing lines up with degree marks on the cam sprocket. You can adjust timing in fractions of a degree (as much as +/-6 degrees) by loosening the cam bolts and turning the bushing with an Allen wrench. Cloyes Hex-A-Just timing sets install under your stock timing cover and can be used in align-bored blocks.
