There's no single "point gap" for a 1972 Chevy 4-cylinder. The correct point gap depends on the specific engine model (there were several 4-cylinder engines offered in Chevy vehicles in 1972). You
must consult your owner's manual or a reliable repair manual specific to your engine.
The manual will specify the correct point gap in inches or millimeters. Trying to guess will likely lead to poor engine performance or even damage.
