Street True Roller Timing Set - SBC Vortec

The Street True Roller Timing Set - SBC Vortec by CLOYES is engineered for small-block Chevrolet engines running Vortec cylinder heads, delivering precision timing control for street performance and daily driving applications. This single-roller design replaces worn or original equipment timing chains and sprockets, restoring accurate ignition timing and cam-to-crank synchronization. Built for enthusiasts and mechanics who demand reliable, repeatable performance without the complexity of exotic drag-racing components, this roller timing set suits budget-conscious builds and restoration projects equally well.

CLOYES' roller design reduces friction and wear compared to traditional silent (leaf-spring) chains, extending service life and maintaining tighter timing tolerances throughout engine operation. The three-keyway adjustable sprocket arrangement allows fine-tuning of cam timing to optimize power delivery across the RPM band—essential when pairing Vortec heads with aftermarket or modified camshafts. Constructed from durable iron and steel components, the kit includes the timing chain, crankshaft sprocket, camshaft sprocket, and related hardware, all pre-assembled to OEM dimensions for direct bolt-in installation without custom fabrication or machine work.

Mechanics and engine builders favor this timing set for rebuilds, restorations, and performance upgrades on small-block Chevy platforms equipped with Vortec heads. Installation requires basic engine knowledge, a socket set, and proper dial-indicator technique to verify timing accuracy; most technicians complete the job within 2–3 hours as part of a larger top-end or full overhaul. Weighing 3.25 lbs and dimensioned at 7.5 x 2 x 7.5 inches, the kit ships complete and ready for immediate use, making it an economical choice for shops and home builders seeking OEM-quality timing control without premium pricing.
