I have found the Borg-Warner SELECT wire sets to be of exellent quality (as good as any big name "racing" wire), and are usually available from lesser sources than all out speed shops, for regular person money.
I get my B/W sets from Pep Boys, and have had one set on my 1982 S10 for over 6 years without problems. I have many customers who run them without problems.
Main thing is to use a spiral core design, as the spiral core is the part that keeps crossfire and misfire problems from happening within the wire sets, and will keep the most spark voltage going to the plugs with any type of ignition system.
I have used the B/W 7mm stock spiral core sets on a few Ford small block, small cap HEI systems I build, for historical accuracy, and have had exellent results, same as with their cut to fit and precut 8mm sets.
If you want "racing" wire, go to a speed shop and get them, just make sure they are a spiral core design.
