In considering ignition options for the 4.2L Jeep engine, can you provide information regarding aftermarket ignition modules suitable for use with the Davis Unified Ignition / HEI distributors. From what I've read, I really like the D.U.I. HEI distributors but am also interested in the Jacobs products designed for standard Jeep distributors. Has anyone gotten these to work together?
I received a reply from MSD saying they do not have an HEI distributor with ignition modules for this configuration.
Thank you.
