Even-number camshaft degree bushing set for dialing in cam timing on Small Block Chevy, Big Block Chevy, and Big Block Mopar engines with a 3-bolt camshaft. These bushings allow precise timing adjustments from 0° to 8° in even-number steps—providing tuning flexibility beyond what multi-keyway timing sets can offer. Advancing the cam can improve low-end torque and throttle response, while retarding it can shift the powerband higher for better top-end power. Kit includes all offset bushings plus a zero-degree bushing.
