Statistical significance does not provide information about the effect size or the clinical relevance. Because of that, researchers often misinterpret statistically significance as clinical one. On one hand, a large sample size study may have a statistically significant result but a small effect size.
An HEI distributor is an upgrade from a points-type distributor. ... Ford and Plymouth, installed four-cylinder engines in their cars.he increased efficiency of HEI distributors stemmed from the incorporation of the ignition wire into the distributor cap, reducing degradation of the spark and loss of energy potential.
Introduction. 1  The distributorless ignition system has been around for the last decade. It was designed to replace the mechanical distributor system (HEI) in controlling the ignition secondary coil voltage. This system is comprised of the following components: 1  Crankshaft Timing Sensor: located in the front of the crankshaft to trigger the ignition system. This sensor consists of a single Hall effect magnetic switch activated by 3 vanes on the crankshaft damper and pulley assembly.
