I recently got my 71 Barracuda back on the road. It is factory stock, except for the points being replaced by a Petronix Ignitor. I started out with 87 non-ethanol gas. The initial timing is set to 8 degrees BTDC. It runs pretty good. I have access to 110 racing fuel and want to blend it with the 87 in order to boost the octane. What octane rating would you recommend?
