What is the advantage of the adjustable crank sprocket?

The 3-keyway crank sprocket allows you to precisely adjust your engine's ignition timing in 4-degree increments. This is useful for fine-tuning performance for different driving conditions or engine modifications.

What makes this a 'Hi-Tech Roller' timing set?

It uses a double roller chain design with heavy-duty large pins, which is stronger and more durable than a stock single row chain. The 'Hi-Tech' designation also refers to the billet steel crank gear and the overall performance-oriented construction.

Does this timing set include any special installation hardware?

The manufacturer's description does not specify if additional installation hardware is included. It is recommended to refer to the manufacturer's installation instructions for a complete list of required parts and procedures.

Product Details

COMP Cams is well-known for making performance engine parts, and this Hi-Tech Roller Timing Set is a solid example of their work for AMC 6-cylinder engines. If you're rebuilding the front of your engine, getting the timing right is crucial for performance and smooth running. This set is designed for '64-'86 AMC 199 and 258 cubic inch 6-cylinder engines, covering a wide range of vehicles like the Jeep CJ series, AMC Eagle, and J-series trucks.

This timing set uses a cast iron camshaft gear paired with an induction-hardened billet steel crankshaft sprocket. The billet steel crank sprocket is a notable feature because it includes three keyways, allowing for 4-degree incremental adjustments to your engine's timing, with a maximum advance or retard of 4 degrees. This adjustability is great for fine-tuning your engine for street performance or race applications. The double roller chain is pre-stretched and heat-treated for durability, and it uses heavy-duty large pins to handle the demands of performance engines. Each set is dynamically balanced and checked for run-out tolerances to ensure it spins true.
