SBC Timing Tab

The SBC Timing Tab from SPECTRE is an essential tuning component for small-block Chevrolet engines undergoing performance modifications or timing verification. Whether you're dialing in ignition timing on a freshly rebuilt 350, 383, or 406 SBC, or fine-tuning a carbureted street engine, this precision tool enables accurate timing mark reading without guesswork. Designed for both novice shade-tree mechanics and experienced engine builders, the timing tab provides a reliable reference point for setting initial timing and confirming top dead center (TDC) position during engine assembly or carburetor synchronization.

Manufactured from durable steel construction, the SBC Timing Tab attaches to the engine block or cylinder head and features clearly marked degree increments for easy reference during ignition timing adjustment. The tab's design allows you to align your harmonic balancer notch or pointer with precise timing marks, eliminating estimation errors that compromise combustion efficiency and engine performance. Its compact 4 x 2.25-inch profile fits cleanly in tight engine compartments, and the lightweight 0.115 lb construction ensures minimal vibration interference during operation. The tab's rigid mounting prevents deflection under engine vibration, maintaining timing accuracy whether you're running a stock distributor setup or a high-performance distributorless ignition system.

This timing tab is indispensable for any SBC engine project—from mild street machines to competition drag racing builds where every timing degree impacts horsepower output and fuel economy. Installation requires basic mechanical skill and hand tools; the tab mounts securely to engine block ears using existing holes or simple bracket fabrication. Engine builders rely on SPECTRE timing tabs to verify timing marks during initial startup, troubleshoot ignition issues, or validate performance carburetor tuning. If you're serious about maximizing SBC performance and repeatability across multiple engine builds, the SBC Timing Tab delivers the precision reference needed for professional-grade results.
