High-Torque Mini Starter

The Summit Racing SUM-829105 is a mini high-torque starter engineered for powerful engine cranking in Chevy SBC and BBC applications. This starter boasts a 2.0 kW (approximately 2.68 HP) motor and operates on a 12V system, featuring a clockwise rotation and a 9-tooth steel pinion gear. Its design accommodates both 153 and 168-tooth flywheels, offering versatility for various builds. With a 3.73:1 gear reduction ratio, this starter is built to handle engines with compression ratios up to 14.0:1, making it suitable for performance applications. The starter is designed with a straight mounting bolt pattern and an aluminum mounting block. Installation instructions recommend ensuring the mounting surface of the engine block is smooth and flat, and to torque starter mounting bolts to approximately 32 ft. lbs. It is important to note that mounting hardware is not included with this starter. While this starter is listed for a wide range of Chevy V8 engines from 262 to 454 cubic inches, and specific Buick models such as the Century, Custom Wagon, Special, Limited, and Sport from various years, there have been reports of compatibility issues and returns due to poor fitment. For instance, one user noted that this starter specifically stated it would not fit a 1966 Corvette, though it might fit other vehicles like Malibus, Chevelles, and Suburbans with similar engine configurations.
