It looks they went into that direction to extract the best possible performance figures under this displacement level and latest emission regulations. E85 and Flex fuel kits could be a solution for those having access to such type of fuel. And of course the worst option would be to supercharge such a high compression engine ...
I bet it's still fine running on 87AKI. It may be optimized for 91/93 but I kinda doubt that being that the US public has such an aversion to using higher octane fuel for some reason. We'll see I guess. I'm excited about the C/R bump, I always run 93 in my cars anyway since they all have at least a 93 Octane tune on them anyway.
