Want to improve ignition....

I did the HEI Ignition Upgrade last spring and it gives me a hotter spark than the Mopar EI system. I know it's a lot hotter because I can run much leaner cruising fuel mixtures than I ever could with the old system. The HEI system is extremely reliable and replacement parts (if ever needed) are plentiful and cheap. See HEI Ignition Upgrade.
