Hi guys. Thinking of upping my wires from 7mm to 8mm but the price doubles for that 1 extra mm. As far as I know the ignition is a stock Motorcraft. A few questions:
Is it worth it or should I stay with the 7mm (I heard the extra mm is insulation only) Will I get better performance?
I know I'll need straight boots for the plug ends but I also have straight boots at the distributor - can I change to 90 degree with no issues?
Being an older (1974) motor, do I need a certain kind of wire for it to work best? I heard some new wires aren't as good as the "older" kind on some applications.
Thanks.
