Octane Used in a GMC 1976 Palm Beach ? [message #181066]

I am looking at a 1976 Palm Beach. I live in Houston so the gas has ethanol. Where I shop, they have 3 grades of gas, 87, 89 and 93 octane.

1. If I get it, which grade should I use?

2. If we rebuild the motor, can I use the 87 grade?

Thanks, Robert
