NOTE: High-Torque Mini Starter A Lightweight Starter 12.75" Flywheel (remanufactured) C High-Torque Starter, chrome B ELECTRICAL IGNITION SYSTEMS 246 STARTERS ALTERNATORS Flywheels with two different diameters are used on Chevrolet small-block, big-block, and 90 V-6 engines. Large flywheels are 14" in diameter and have 168 teeth on the starter ring gear. Small-diameter flywheels are 12.75" in diameter, with 153 teeth on the ring gear. This difference in flywheel diameters requires two distinct starter housings. Starter noses used with large-diameter flywheels have two offset bolt holes, while starters for small flywheels have two bolt holes which are parallel to the back of the block. Most Chevy blocks are drilled for both types of starters. A. 12361146 High-Torque Mini Starter This gear reduction starter is designed for 1958-1996 V-8 and all 90 V-6 engines.
