Rich, This may be dangerous using my name and DMCH on the same line.:-))

Are the wires working out. If you want to gap the plugs wider then I would
go to the 8.5 mm MSD I build.

Since my name was used, I'll chime in. :)

I totally agree. By over-gapping my plugs, I forced other components
to bear the electrical load and they wore out -waaaaay- faster than
I expected.

I'm running John's silicone wires and all other items are factory
spec. I've put several thousand miles on the existing setup and my
wife still crabs at me for outpacing her PT Cruiser during two-car
trips.
