True Roller Timing Set - BBC Adjustable

The True Roller Timing Set - BBC Adjustable by Cloyes is specifically designed for big-block Chevrolet engines, providing builders and enthusiasts with the precision needed for optimal ignition timing control. This timing set is ideal for various applications, including street machines, competition engines, and classic hot rods.

Featuring roller-type sprockets, this timing set minimizes wear and friction compared to traditional gear designs, which helps reduce parasitic drag and ensures consistent timing retention. The adjustable design includes precision keyways and indexing, allowing for incremental timing curve optimization without guesswork, making it essential for carburetor tuning, fuel injection mapping, or boost calibration.

This timing set is particularly beneficial for BBC engines from the 1960s to modern stroker builds, especially when using aggressive cam profiles, forced induction, or nitrous systems. Installation requires removing the timing cover, a standard procedure for any BBC rebuild, ensuring that reliability and performance are maintained in both street and strip applications.
