Re: spark plug gap for 53 Clipper and jack position

The spark plug gap increases due to erosion of the electrode and wire as the car is driven. If you start with .025, in 10,000 miles it may be .028 or .030, then itn needs to be regapped.. A few thou here or there makes little difference but setting the plugs at .020 or .040 will make problems. Dont overthink too much just enjoy your Packard
