I think i might answer my own question here. But any other feedback is great.

drove to work yesterday 20 miles. after getting off the freeway my car felt like it was missing and the idle was a little rough.

Same thing again today but not as repetitive.

Once i get going i dont notice it. Only at idle.

In the past It was a spark plug wire ARCing off the header. I have been through 2 sets of wires. Some MSD super conductors did it after about 5 months and now Im on some Accel wires.

If it is the wires. How do I keep killing them? Is it just the heat? Am i gonan have to shell out the cash for some ceramic boots

ANy other opinions are welcome.

Oh yeah when this happens the voltmeter hops around alittle or stays around the 11-12 range.

Most of the time it is 13 sometime 14.

This is with running no elctric fan. No radio on.
383 600 cfm carb, headers and a 7 month old Accel HEI setup.

Still running an external regulator? The voltage looks low at idle.

 

[mykes68]

external regulator? You mean that box up near the headlights right?

Only sometimes. This morning is wasnt jumping around at idle but i could tell there was a slight miss in the idle. it sounds totally normally just every once and ahile i get a "putt putt".

If that makes sense.

Last night while driving home with the lights on voltmeter was jumping around a little.

Yeah, the little box by the headlights. Might consider converting to an internally regulated alternator. Should stop that bouncing at idle. If dollars are low look for a recently rebuilt one at the U pick parts in Sun Valley. They give a free warranty and Kragen will test it for free.
You are providing a full 12 volts to the HEI and not running it through the old resistor wire? Doesn't sound like you are using that old wire.

Just pull some boot insulators from a *whisper* f-o-r-d if heat is killing the plug wires, dont buy that expensive crap

How you burned an MSD super conductor set is beyond me...those things have a bigger boot than my little brother

Good luck with the other problems
