I have heard different things from different people about AV gas. The motor in question is a 460 bored .60 over (472), flat top pistons, big cam, edelbrock aluminum performer rpm heads, torker intake, and has 11.5:1 compression. It is in a jet boat. Basically, my question is does antone run AV gas in motors like this? I've heard its bad, I've heard its fine with mistery oil, I've heard mistery oil is no good. I've heard it all. What octane should the fuel be. I appreciate any advice.
