Is you do a thing for 1000 hours your considered an expert. Just 994 more hours of wire replacement to go.

More like, 6 more hours to go.  My expertise comes much more slowly, so probably something like 600,000 hours.

The MSD wires currently in use are rated at 50 Ohms/ft.  I suspect something happened to the wires, but I am seeing everything from that resistance to 350 Ohms/ft.  Lower resistance would seem to be better, but what is right?

I do notice that these MSD wires seem to reduce power.
