    EFI maybe with proper tuning. Carburetor, no way.
    E85 has an octane rating of around 105.

    We've run 14.5 to 1 with no issues. Once I get through the upcoming carb challenge I plan to try it on my 15.5 to 1 SB2. If you do want to try it start conservative on the timing and sneak up on the tune.
