I took a look in the archives and did not find much.Is the hei ignition transplant from a gm truck the way to go on my 86 cj 7 with the 258.I am presently going to do somethink about my leaking carb { a holley of unknown origin }I have been lead to a motorcraft 2100 and would not mind a ignition upgrade.Question is,is the hei still an upgrade of choice and are there some write ups on both the carb and hei? aloha Dave <img src="/forums/images/graemlins/lol.gif" alt="" />
