Timing Tab for LS Conversion

The Timing Tab for LS Conversion by Allstar Performance is an essential reference tool for engine builders and mechanics performing LS engine swaps into non-LS platforms. When converting a traditional engine bay to accommodate an LS powerplant, you need precision timing alignment during initial startup and tuning phases. This timing tab serves as a critical visual reference point, allowing you to accurately set ignition timing without guesswork—a task that demands repeatability and accuracy to avoid detonation, poor fuel economy, or engine damage during the break-in period.

Engineered by Allstar Performance, a trusted name in engine management and timing accessories, this timing tab is designed to mount on the crankshaft pulley or timing cover in a way that allows you to read timing degrees relative to top dead center (TDC). The compact 2.65 x 0.9 x 4-inch form factor and minimal 0.04-pound weight make it easy to install without interfering with serpentine belts, hoses, or other engine bay components. Made from durable materials to withstand vibration and heat, the tab provides clear degree markings that align with your timing light for accurate readings across the full advance curve.

LS conversion enthusiasts benefit most from this timing tab during initial tune-up work, especially when swapping into Camaros, Corvettes, trucks, or other platforms that didn't originally house LS architecture. Whether you're running a carburetor with a traditional distributor or a fuel-injected system with a modern ECU, establishing baseline static and dynamic timing is non-negotiable. This tab eliminates confusion and ensures repeatability across multiple test sessions—critical when dialing in cam timing, checking ignition advance curves, or troubleshooting drivability issues on your freshly built LS platform.
