SBC Hex-A-Just Timing Set - w/BBC Crank Snout

The SBC Hex-A-Adjust Timing Set with BBC Crank Snout from CLOYES is engineered for serious small-block Chevrolet builders who demand precision cam timing control without the complexity of full adjustable systems. This timing chain set is designed specifically for small-block platforms running big-block crankshaft conversions, a popular upgrade among street and competition engine builders seeking increased displacement and torque characteristics. The hex-adjustable cam gear allows real-time timing refinement, letting you dial in optimal ignition advance for your specific fuel octane, compression ratio, and induction setup—critical for maximizing both performance and engine longevity.

The mechanical design centers on CLOYES' durable chain and gear architecture, with the BBC crank snout accommodation allowing seamless integration into hybrid small-block/big-block builds. The hex-adjustable feature uses a simple wrench interface to shift cam timing in increments, eliminating the need for external belt drives or complex electronic phasing systems. This straightforward mechanical approach proves invaluable during dyno tuning or street testing, where timing changes can be made without breaking down the front cover. The timing set's compact geometry preserves stock accessory mounting points while maintaining proper chain tension and wear characteristics across a wide RPM range.

This timing set is ideal for engine builders performing BBC crank conversions on small-block platforms, hot rodders upgrading street engines, and racers fine-tuning cam timing for variable fuel grades and boost conditions. Installation fits standard small-block Chevrolet covers and front-end accessories, though the BBC crank snout specification requires compatible crankshaft geometry. Whether you're maximizing street power in a 383-stroker or optimizing a competition engine, the SBC Hex-A-Adjust Timing Set delivers the adjustability and reliability serious builders expect from a CLOYES timing system.
