Plus, there is a mechanical advance assembly that is mounted on top of the distributor shaft making it easy to adjust the advance to meet your needs. Another great feature of the Ready-to-Run distributors is their simple installation! All you need to do is connect three wires and you’ll be cruising!

Whenever you are planning an engine overhaul or a cam change, don’t forget the valve seals.

Product Features:
  • Work with .530″ guides and 3/8″ valve stem diameter
