SBC Timing Tab - Chrome

The PROFORM SBC Timing Tab in chrome is an essential ignition timing reference tool designed for small block Chevy engine builders, performance tuners, and shade-tree mechanics who demand precision during initial setup and ongoing maintenance. This timing tab bolts directly to your engine's timing cover and aligns with the harmonic balancer's timing marks, providing a fixed visual reference point that eliminates guesswork when setting ignition timing with a timing light. Whether you're dialing in a fresh rebuild, troubleshooting stumbling idle conditions, or fine-tuning carburetor and ignition curves, accurate timing marks are non-negotiable for peak performance and fuel economy.

Constructed from durable steel and finished in bright chrome plating, this timing tab is engineered to withstand engine bay heat cycles and resist corrosion while maintaining clear visibility of critical timing degrees. The 8-inch OD balancer compatibility ensures proper alignment with stock and many performance harmonic balancers commonly found on small block Chevy applications. The compact, lightweight design (0.12 lbs) minimizes assembly complexity and fastens securely to the timing cover without interference to water pumps, belts, or accessory drives. Chrome finish not only looks professional but provides protection against rust and makes timing marks readable under both daylight and timing light illumination—critical when working in dimly lit shops or engine bays.

This timing tab is ideal for anyone rebuilding or modifying a small block Chevy—from street engine builders to competition tuners preparing engines for the dyno. Installation is straightforward: bolt the tab to the timing cover using existing fastener holes, then verify alignment with your harmonic balancer's degree markings. It pairs seamlessly with standard timing lights and magnetic pickup tools, making it an affordable investment that pays dividends in diagnostic accuracy and engine optimization. Whether you're running a stock 350 or a high-compression stroker, having a reliable, visible timing reference eliminates variables and puts control firmly in your hands.
