Performance Distributors 1331 Details

The Performance Distributors 1331 D.U.I. Mechanical Advance Lock Plate is designed to eliminate the mechanical advance function in GM HEI distributors by replacing the factory weight and spring assembly and locking the distributor shaft in a fixed position. This provides total ignition timing throughout the entire RPM range, making it ideal for racing applications where timing is controlled by an aftermarket ignition system or precise engine tuning. Easy to install and engineered for reliability, the lock plate is compatible with GM HEI distributors and is intended for high-performance, non-computer-controlled engines that require consistent, fixed ignition timing for maximum tuning flexibility and repeatable performance.
