For a crisper, smoother running engine, replace your stock HEI module with the Dyna-Module. The Dyna-Module has more electronic dwell in it to provide more coil saturation time. The additional saturation time allows the coil to produce a more intense spark, improving throttle response and low end power! Installation is easy as the Dyna-Module mounts in the stock location of an HEI module with no modifications. Fits all V8, 6 Cylinder and 4 Cylinder DUI / HEI Distributors. Also fits Performance Distributors Chevrolet, Pontiac and Dodge Tri-Power Ignition Systems.
