Leaded fuel, but they don't make it anymore. So most muscle car guys put 93/94 octane in and some an off the shelf additive. I know some guys run 87 octane only. Depends on how much driving you do. Check online of some muscle car forums for more opinions.

Premium (93+ octane) with a bottle of lead substitute at each fill up. If you have problems with dieseling, and/or pinging use a bottle of octane booster at each fill up as well. That was the regimen I used with my '70 Catalina. It had the V8 400. Worked very well. HTH. -Jim

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.....
