8in Timing Tab

The 8in Timing Tab by Mr. Gasket is an essential tuning tool for any serious small block Chevy engine builder or performance mechanic. This steel timing tab attaches directly to your harmonic balancer, providing a precise reference point for setting ignition timing with dial-back timing lights or degree wheels. Whether you're dialing in a stock rebuild, a mild performance cam swap, or a full race engine, this timing tab eliminates guesswork and ensures your spark timing is locked in at the exact specification your engine demands.

Constructed from durable steel and finished in chrome for corrosion resistance and visibility, the 8in timing tab is engineered to mount securely on an 8-inch outer diameter balancer. The tab's rigid design prevents deflection under engine vibration, maintaining timing accuracy cycle after cycle. The chrome plating not only protects against rust in high-temperature engine bays but also reflects light, making TDC and timing degree marks visible even in dim lighting conditions. At just 0.09 lbs, this lightweight component adds negligible mass while delivering precision that directly impacts combustion efficiency and engine response.

Mechanics and engine builders working with small block Chevy platforms—from 283 to 400 cubic inch engines—rely on this timing tab for initial setup and ongoing diagnostics. It's equally valuable during initial startup tuning, carburetor synchronization, and post-rebuild verification. If your 8-inch balancer lacks a timing reference or the original mark has worn away, this Mr. Gasket tab restores full timing control. Installation is straightforward: align the tab with your balancer's mounting surface and secure it per your engine's specifications. For any shop or enthusiast committed to precision engine management, this timing tab is an indispensable accessory.
