I recently purchased a digital timing light to help me tune my ignition and double check the centrifugal advance in my distributor. While I do own a 1955 Ford, the distributor is from a 60's F100 therefore, it does have centrifugal mechanical advance. There is also an ACCEL 2020 points eliminator kit installed in place of the points and condenser.
