Davis Unified Ignition Dyna-Modules
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.

MSD Iron Distributor Gears
MSD puts their years of experience to work in making these top-notch iron distributor gears. Their high grade, ductile iron is micro polished for a smooth and scuff-free finish then Melonite QPC coated to reduce friction and initial wear. Excessive clearance causes timing fluctuation throughout the rpm range, resulting in lost horsepower, so MSD also designed these oversized gears for tighter mesh between the camshaft and distributor drive gears.
