the HEI distributor is one of the best mods you can do to a 4.2. add a different carb and the engine comes alive. I've run mine for almost 5 yrs with no problems.

I agree. I put mine in yesterday and wow, what a difference. I still have a misfire, but after the dizzy, 8mm plug wires, new plugs, and the mc2150 carb, I think it may be in the valves

I have a weber carb and I didn't even time mine and it purrs like kitten... I have a slight ping when on the freeway and climb a hill so still need to fine tune it even out of time a little it runs a hell of a lot better... I'm impressed!

That slight ping is called detonation. If you love your engine you will set your timing..

Yeah, do your timing or it could go boom.
