i use 87 octane...here in TX, the elevation is pretty low, so you can get by with using a lower octane gas and not have ping or detonation.

93 here in Michigan in my '66 289 coupe. I couldn't believe the difference it made, even after I had hardened valve seats installed. Kindof stinks, though, that I'm not paying $1.89/gallon.

I always use 92 octane from the same 76 station as much as possible. I'm running close to 10:1 compression and mine likes the 92. If it's not 92, I can tell in the first 20 feet.

65 FB "J" 302 lots of mods. 94 GT K&N only.
