wire loom tubes
I was thinking about the early 21-A style wire loom tubes that run by the manifold and was thinking that little dudes create a good atmosphere for cross-fire. Has anyone had trouble with these things causing that? I like the way they smooth out the wires, but a smoother idle is much more important to me. Maybe the 6 volts didn't have a cross-fire problem but a 12 volt or electronic ignition may.

Clayt,
That shouldn't make any difference - the voltage to the coil is dropped by a resistor in a 12V system. Actual voltage across the points is only about 4.5v if I remember right.
Those wire looms do cause problems for some guys - mostly age deterioration of the wire's insulation from what I've heard.
Also a consideration is the firing order and how the wires touch each other. I've seen some crossfire trouble without the looms where 1/2 and 8/6 wires contact each other. firing order 15486372
On my '48 driver, I've even slipped plastic loom material between those wires that are prone to trouble. I don't like the look, but it sure saves headaches.
