Sbc 6-3/4in Timing Tape

The Mr. Gasket SBC 6-3/4in Timing Tape is an essential tool for any serious small block Chevy builder or performance tuning enthusiast working with balancer-mounted timing references. This precision timing tape attaches directly to the harmonic balancer of 6.75-inch outside diameter applications, providing a reliable visual index for setting and verifying ignition timing during engine diagnostics, carburetor tuning, and performance modifications. Accurate timing control is fundamental to engine efficiency, emissions compliance, and peak horsepower delivery—making this tape indispensable for both street and race applications.

Manufactured by Mr. Gasket, a trusted name in ignition and fuel system products, this timing tape features clearly marked degree increments that allow you to reference timing marks with a timing light or degree wheel. The tape adheres securely to the balancer rim without slipping or warping, maintaining accuracy across repeated use and varying engine temperatures. The design is optimized for small block Chevrolet engines, ensuring compatibility with standard 6.75-inch harmonic balancers commonly found on 327, 350, and 383 platforms. Its compact form factor—measuring 3.25 by 0.65 by 5.85 inches—keeps storage simple while the minimal weight ensures zero impact on balancer balance characteristics.

Mechanics and engine builders rely on this timing tape when establishing baseline ignition advance, tuning distributor curve boxes, optimizing carb idle timing, or validating cam timing on freshly assembled short blocks. Whether you're performing a compression test, chasing a knock condition, or dialing in initial timing before hitting the dyno, having a precision timing reference eliminates guesswork and prevents costly mistakes. This tape is a must-have for anyone working on classic small block Chevys, street rods, or vintage performance vehicles where timing accuracy directly influences throttle response, fuel economy, and engine longevity.
