Description

Holley s EFI Crank Trigger Kit is engineered to provide an accurate crank speed & position signal to Holley EFI systems in the most-demanding, high horsepower, racing applications. Crank position is measured every 10 degrees as opposed to every 45 degrees for a standard 4-Magnet, MSD style Crank trigger. It is designed for use on early model small block Chevy applications using a standard ATI or Fluidamper style balancer up to 7-1 4 in diameter.
