A: The 8140 has 1.4 OHMs primary resistance and will need a ballast resistor when used with a point style distributor. The 8145 has 0.7 OHMs primary resistance and will require a ballast resistor when used with a Unilite or MBI distributor.
A: Yes, you will need a ballast resistor when using Accel Super Coil #140001 with a Unilite or MBI distributor. To use with a points style distributor, additional resistance is needed to get to 3.0 OHMs.
A: Accel #35366
A: You will need to look at your original coil. If you have red and yellow OEM primary wires, use Accel #140003. If you have red and white OEM primary wires, use Accel #140005.
A: This varies depending on your current spark plug.
A: .045 is a good starting point. Check your plugs after 100 miles of driving. The white porcelain around the electrode of a properly gapped plug should have khaki tan coloration. If the plugs look black, close the gap by .005 to .040. If the porcelain is white, open the gap by .005 to .050 to cool the operating temperature of the plug.
A: Accel # 60116
A: GM V8 1957-74: Accel #2010
Ford V8 1957-74: Accel #2020
MOPAR V8 1961-73: Accel #2020
A: Insert a 3/32 hex key into the vacuum port and turn clockwise to increase the advance. Turn counterclockwise to reduce the vacuum advance.
