recommended fuel octane for 1970 Dodge 340?

There is leaded gas available in Oregon.......94 octane at select stations. I buy mine currently for $4.73 per gallon....and use it in all my Carb equipped vehicles.....

I have a 71 inline6 Coronet that I brought back to life and found a place that sells 84 octane will it damage it?? I'm using 90 during my break in period after the block shaving job

84 octane? I doubt there is such a thing and I don't know of any car other than a model A that would run on it.
