COMP Cams Hi-Tech Roller Timing Set CRB/Cr

This is the COMP Cams Hi-Tech Roller Timing Set, designed for Mopar big-block engines like the Chrysler 383, 400, 440, and the legendary 426 HEMI. A timing set is crucial because it synchronizes the camshaft and crankshaft, ensuring your engine's valves open and close at precisely the right moment relative to the pistons. Getting this timing right is key for smooth running and optimal performance.

This particular set features a well-built cast iron camshaft gear paired with an induction-hardened billet steel crankshaft sprocket. The crank sprocket is a standout feature, offering three keyways for 4-degree incremental adjustments, allowing you to fine-tune your engine's timing up to 4 degrees either advanced or retarded. This adjustability is really helpful when you're building a performance engine and need to dial in the cam timing for specific power bands or street manners. The double roller chain is pre-stretched and heat-treated for durability, and it uses heavy-duty large pins for added strength, making it suitable for both street performance and dedicated race applications.

When installing this, pay close attention to the degree marks on the adjustable crank sprocket to achieve your desired timing. It’s a solid option for anyone rebuilding or upgrading the timing components on their classic Mopar big-block.
