MSD or Blue Streak wires?
For a performance engine, what is important is to use spiral/helical wound wires. Resistance is NOT critical. Many years back, Circle Track tested about a dozen wires on a 400 hp SBC engine. There was a few hp difference, but the highest hp was NOT with the lowest resistance wires!
Helical wires create an inductor. So now you have resistance, inductance & capacitance in the mix.
