Title: hei or external ignition
Post by: hotrod87 on May 31, 2009, 12:22:47 pm

My engine starts to miss fire on high rpms.  I was told I could get a hotter hei distributer to stop this, or would this be a good oppetunity to change to an external ignition?   Is it hard to change from hei to external?

It's not hard to retrofit an MSD or the like. It's definitely the most overlooked upgrade you can do. You probably just need a tune up though.

MSD is good or a lot of people are buying these and I haven't heard any horror stories yet
