Bb Chevy Chrm Timing Tab

The Bb Chevy Chrm Timing Tab from TRANS-DAPT is an essential small-block Chevrolet ignition timing reference component designed for engine builders, performance tuners, and mechanics who need precision timing mark visibility during initial startup and tuning procedures. This polished chrome timing tab serves as a critical visual reference point on the front of the engine block, allowing you to accurately verify and adjust ignition timing using a timing light without relying on factory markings that may be worn, obscured, or missing on older or modified engines. Whether you're rebuilding a classic muscle car, installing a crate engine, or performing a complete engine swap, this aftermarket timing tab ensures you can dial in exact timing specifications.

Constructed from durable chromium-plated steel, the Bb Chevy Chrm Timing Tab features clear, legible degree markings that remain visible even under engine bay lighting and heat cycling conditions. The design mounts securely to the small-block Chevy timing cover, positioning the reference scale directly in line with the crankshaft pulley damper for quick, accurate timing light readings. The polished chrome finish not only enhances appearance in show applications but also provides superior visibility compared to painted or powder-coated alternatives, making it easier to see exactly where the timing mark aligns during both static and dynamic timing adjustments. This component eliminates guesswork and ensures repeatable results across multiple tuning sessions.

Mechanics and engine builders working on small-block Chevrolet platforms—including 283, 327, 350, and 400 cubic inch engines—will find this timing tab indispensable for carburetor synchronization, ignition curve verification, and emissions compliance tuning. Installation is straightforward, requiring only basic hand tools and a few minutes to mount securely to the timing cover. The compact size (4.65 x 2.2 inches) and light weight (0.14 lbs) make it an easy addition to any engine build without affecting balance or clearance. TRANS-DAPT's reputation for quality small-block Chevy accessories ensures this component will withstand engine heat and vibration for years of reliable service.
