All fuel is pretty much the same because there are only three manufactures refining fuel. The difference is what is added by the individual sellers that can make a difference like detergents, etc. If you are running aluminum heads and are under 10:1 mid grade could work depending on the overall timing/setup on your engine. Because of the 454 torque and the possibility it could be iron headed I would stick with premium just to be safe. I use premium because I like the extra octane and the cleaners in shell V-power. I also run STP every few months to get rid of water buildup.
