Davis Unified Ignition Dyna-Modules

4.64 out of 5 stars 132 Customer Reviews

Replace your stock HEI module with Davis Unified Ignition Dyna-modules for a crisper, smoother running engine. They have more electronic dwell than your stock, so the coil saturates longer and produces a more intense spark. Dyna-modules are available in different pin quantities to meet your application, and mount easily on the side of your distributor housing with minimal wiring. Quicker starting, better throttle response, and more low-end power can be gained with Performance Distributors Dyna-modules.
