Switched to HEI

Opening the gap will give the full benefit of HEI. But if you go too far you will suffer mis-fire under WOT at low rpm (freeway ramps). I got that in my 2.4L at the factory 60 mil, so reduced to 50 mil and no more problems (Chrysler TSB for turbo version).

If you have a small block (nice to tell us), you can use wires for a Magnum V-8 engine. I grabbed some from the JY cheap. I think factory. They are silicone jacket, w/ each one labeled "cyl 1", ... MSD makes a set too. Of course, the distributor end is for a male terminal on the cap, but those who buy the Ready-to-run HEI distributor ($45 ebay) usually get that.
