What is the point gap for an Olds 455 V8?

There's no single "point gap" for an Oldsmobile 455 V8. The correct point gap depends on the *specific year* of the engine and the *type of ignition system* it uses (points-type ignition or electronic ignition).

Older 455s with points ignition will have a different gap requirement than later models or those converted to electronic ignition. Consult your engine's specific shop manual or a reliable resource like a Haynes or Chilton repair manual for the correct specifications. A general range might be between .016" and .020", but that is not universally applicable and could lead to misfiring or other problems.
