Holley EFI Crank Trigger System – BBC

Holley’s EFI Crank Trigger Kit is engineered to provide an accurate crank speed and 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″ diameter.

• 8″ diameter, 1/4″ thick, billet steel, 36-1 tooth, crank wheel with Black Zinc Oxide finish for superior corrosion resistance and striking good looks
• Crank wheel centers off the balancer’s hub, eliminating the need for a centering ring
• All billet, 6061-T6 aluminum sensor mounting bracket with “bright-dipped” black anodized finish and Laser etched Holley EFI logo
• Custom 3-wire, ferrous-target, Hall-effect sensor with M12X1MM threads for finer gap adjustment
• All grade 8 and Mil. Spec mounting hardware
