69-91 SBC Timing Tab - 6.75/7.00 Balancer

The PROFORM 69-91 SBC Timing Tab for 6.75/7.00 Balancer is a precision timing reference tool designed for small-block Chevrolet engines built between 1969 and 1991. This component serves as an essential accessory for engine builders, performance tuners, and restoration specialists who need accurate timing degree verification during initial startup, dyno testing, or carburetor synchronization.

Manufactured by PROFORM, a trusted name in engine timing and diagnostic equipment, this tab attaches directly to the harmonic balancer circumference and works in conjunction with the degree markings cast or etched into the balancer itself. The tab's precise alignment allows you to track top dead center (TDC) and read timing advance in real-time using a stationary pointer mounted on the timing cover. The lightweight design—at just 0.1 lbs—minimizes any rotational inertia or balance disruption to the harmonic balancer assembly.

Serious engine builders and performance shops standardly use this timing tab during engine commissioning and tuning sessions. It's particularly valuable when verifying vacuum-advance settings and ensuring optimal engine performance. The 6.75 and 7.00-inch balancer compatibility ensures fitment across a wide range of SBC applications, from stock 350 engines to modified 427 stroker combinations.
