Bob; John,
I use MSD SuperConductor wires, and NGK
B9EGV plugs with the LS1 coils. Plugs work great, but don’t last
real long. The last set I started to notice some roughness below 2000 rpm
after about 25 hours. Fresh plugs made it go away. I think the
prior set lasted longer; so maybe an unusual circumstance.

I’m
using the LS-1 coils for my 20B, what type of plug wires should I use? My
longest run is 24 inches.

I pulled the plugs out, they were
the ones that came from Atkins, these plugs looked new on the outside, but were
used to keep dirt out of engine, as they were used and plugged full of
carbon. The plugs are NGK T-SD 11A; L-SD 10A. I see where Lynn and
AL are using NKG R6725-11.5's, Is this plug used as a leading and trailing
plug? At any rate, I need to get some new plugs. JohnD
