Specifications

This conversion kit is specifically designed for Prestolite 6 Cylinder Distributors. The core of its technology lies in a sophisticated electronic pickup that senses current levels in the ignition coil. It then actively adjusts the dwell, which is the period the coil is energized, to maintain peak energy output across the entire RPM range. The product details highlight that it develops, on average, four times more available energy between 3000 and 5000 RPMs, and twice as much plug voltage compared to point-type systems. This significant increase in ignition energy is crucial for maximizing combustion efficiency and power in older engines.

The increased energy output from this kit translates directly into a stronger spark. This means a more complete burn of the fuel-air mixture, leading to improved horsepower and torque, especially at higher engine speeds where traditional points systems often falter. It also contributes to a more stable timing curve, reducing hesitation and improving throttle response. For those looking to extract the most performance from their classic six-cylinder engines, this specification is key.
