Still running rough and backfiring

Guys, read the first post, NO EXTENDERS. Doesn't mean that there isn't a bad wire though. What are Hemi wires anyway?

 

I can't find the specs on these wires, are they stainless steel wound wires? From the pics you might try sliding the covers out of the way and directly connecting the plug boots to the plugs.

Also finding one plug that was clean and smelled of fuel means likely no spark to that one plug quick check is to swap wires and see if the problem moves.

 

Having good resistance does not limit them cross arcing to the wall. Just for giggles, toss a few drops of fuel down each spark plug well and fire her up to see what happens... ;-)

Have you checked what your alternator is giving out in volts check through the rpm range I had similar problems and found out the rectifier was producing arout 18 volts and this killed the ignition I run Pertronix. Once fitted a new rectifier problems solved though had also had to replace the petronix

 

thats awesome
job well done

 

"switching plugs" Right...
