Moroso 57-75 GM Non HEI Advance Curve Kit

Moroso is well-known for making performance parts for racing and street applications. This advance curve kit is designed for GM non-HEI distributors from 1957-1975. It helps you fine-tune your engine's timing for better performance. By adjusting the advance curve, you can optimize how the spark timing changes with engine RPM, which can lead to improved throttle response and a smoother running engine.

This kit includes the necessary components to modify the stock advance mechanism. Installing this kit allows you to tailor the ignition timing to your specific engine build or driving needs. It's a straightforward way to get more out of your classic GM ignition system without needing to replace the entire distributor.
