Short answer: The biggest gap you can do without getting a misfire. This is usually somewhere between .030 and .042, but can differ with ignition system.
Oh, and I never trust the factory settings. I have had good factory settings, and I have had bad factory settings. One bad factory setting can really make you mad when troubleshooting a misfire.
Oh, and I think he meant .035, not 0.35, since 0.25 is a quarter of an inch.

.032 We've had a 66 Mustang with a 289 in the family since 1968. Good car!

My Chilton Manual for 1966 says .034 for a 289.
Gap new plugs before you put them in.

Just from memory, it was .016" gap on the points and .035" on the plugs. It's been a long time since I've done that.
