Spark wire length - '65 389
I'm going put new spark plug wires on my GTO, the old have a couple couple cuts and are way too long. It has GM HEI distributor and I want the wires to go behind the heads to the plugs instead of over the valve covers. Does anyone know what length each wire should be and will this a cut to fit application or... is there a brand/part number for 8 mm wires that are a custom fit?
Also, does anyone know the diameter of the stock harmonic balancer (where the timing marks are)? I want to put on timing tape and do not have calipers large enough to get a good measurement.
