when you are looking at plug wires;
consider the angle of the plug-ussualy 90 degrees if you have headers or you can get an assortment etc also consider the thickness of wire.
btw; I don't remember where I saw it, but msd has a new dist cap with a "corrected firing order" this so that you dont have to cross spark plug wires. curious as to how it works. might even check one out some day.
