Ron's motor originally had exhaust gas recirc, that means the compression ratio is 8.0:1. I normally twist the distributors on those motors for around 20 degrees initial advance and hook the vacuum advance canister straight to "ported" vacuum, no little vacuum signal control goodies in between. (the factory spec for that motor is 16 degres initial, so 20 degrees shouldn't give you any concern) I leave the vacuum retard side of the canister disconnected, always.

Even so, you should be able to operate the motor on 87 octane fuel. If the motor tends to "run on" or diesel with 87 you may need to switch to 89. Operating on the lower octane fuel will actually improve your fuel economy.
