Proform HEI Distributor Buick 350

6Put an HEI under your hood!!!
Proform's HEI distributors have a variety of improvements over stock HEI distributors, such as a 50,000 V coil, a premium hi-dielectric cap with brass terminals, both upper and lower bushings for added durability, a low-saturation ignition module, and no voltage-reducing ballast resistors. These units offer calibrated advance curves that are optimized for maximum combustion efficiency, and the elimination of detonation damage and throttle ping. The distributors offer longer-term durability and a higher voltage spark that permits a bigger spark plug gap, resulting in more power and reduced plug fouling. By eliminating the stock AMC ballast resistor, you'll get more ignition voltage, resulting in an improved spark. Another advantage to switching to HEI is access to easily-found HEI replacement parts. They're easy to install by connecting one 12 V hot wire to the distributor, making them a quick performance upgrade.
