EFI™ Crank Trigger Kit (556-113) by Holley®. 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 BBC Chevy applications using a standard ATI or Fluidamper “style" balancer up to 7-1/4" in diameter. Designed utilizing the latest technology, this product by Holley features premium quality and will perform better than advertised. Perfect for your vehicle and lifestyle, it is manufactured to meet or exceed stringent industry standards.
