Performance Distributors 000666 Dyna-Module GM HEI 4-Pin Ignition Control Module

The Performance Distributors Dyna-Module is a high-performance ignition control module engineered to improve the performance of GM Vortec engines through increased electronic dwell, which extends coil saturation time and produces a more intense and longer duration spark in the combustion chamber for improved throttle response and low-end power.

Key Features:

• Increased electronic dwell provides additional coil saturation time for more intense spark output
• Direct factory replacement that mounts in original factory location with no modifications required
• GM HEI 4-pin design for Vortec applications
• Suitable for street, racing, off-road, and marine applications
• Compatible with any HEI-style coil

Applications:

• Fits Vortec 4.3L V6, Vortec 5.0L-5.7L, and 7.4L V8 engines
• Also fits 1994-1995 LT-1 Corvette, Camaro Z-28, Firebird, and Trans Am
• Designed for 1994-1996 GM distributor applications

This Dyna-Module is the same high-performance module used in all Performance Distributors D.U.I. (Davis Unified Ignition) distributors, offering a cost-effective upgrade to enhance ignition performance on stock GM HEI distributors. The improved spark characteristics result in better combustion efficiency, smoother running, and improved overall engine performance.
