Holley's EFI Crank Trigger Kit 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. Crank position is measured every 10 degrees as opposed to every 45 degrees for a standard 4-Magnet, MSD “style” Crank trigger.
•8” diameter, 1/4” thick, billet steel, 36-1 tooth, crank wheel with Black Zinc Oxide finish for superior corrosion resistance & striking good looks.
