Sbc & Bbc 8in. Timing Tape

The SBC & BBC 8-inch Timing Tape is an essential tool for automotive enthusiasts and professional mechanics working on small-block and big-block Chevrolet engine builds. Precise timing degree verification is critical when tuning ignition systems, installing performance camshafts, or diagnosing combustion issues on the dyno or street. This timing tape eliminates guesswork by providing clear, visible degree markings directly on your crankshaft damper, allowing you to quickly verify TDC (top dead center) and adjust initial timing without expensive diagnostic equipment.

Mr. Gasket's timing tape design features an 8-inch circumference format scaled for standard SBC and BBC damper sizes, with clear degree increments marked at critical intervals—typically BTDC (before top dead center) and ATDC (after top dead center) zones that engine builders rely on for accurate base timing and advance curve mapping. The adhesive-backed construction bonds securely to the damper's outer surface, remaining stable through heat cycles and extended engine operation. The high-contrast marking scheme ensures visibility even under workshop lighting or engine bay shadows, eliminating the need for timing lights when performing initial setup or verification checks on freshly assembled engines.

This timing tape is indispensable for street rodders, circle track competitors, and engine builders preparing SBC or BBC platforms for carbureted or fuel-injected applications. Whether you're validating ignition timing after a custom cam installation, troubleshooting cold-start issues, or optimizing distributor recurve curves for peak power delivery, the visual reference this tape provides accelerates diagnostics and reduces setup time. Installation is straightforward—clean the damper surface, apply the tape at TDC, and confirm alignment using your engine's existing timing mark or a degree wheel. Compatible with any SBC (262–400 cubic inches) or BBC (396–502 cubic inches) engine using a standard harmonic balancer.
