Champ Pans GM HEI Distributor Advance Lockouts

5.0 out of 5 stars 3 Customer Reviews

Champ Pans GM HEI distributor advance lockouts offer a quick and efficient way to lock out timing on GM HEI-style distributors. These lockout plates are made from high-quality material and are offered in two styles: mechanical and vacuum advance. The mechanical advance lockout plate replaces the mechanical advance weights—and simply slides over the pins on the shaft and the advance assembly to eliminate any mechanical timing advance. The vacuum advance bolts in place on Circle Track HEI distributors, but will work on most GM HEIs. Order the distributor lockout plate designed for your application.
