**600hp sbm block limit? Or is it bs!!**

Detonation will kill any engine block, I think this is/was the major factor. That is why I run my car on 114. It might be a tad faster on 110 but I'm not risking it. For the measely gain in ET and the .50 cents a gallon more it's just not worth it.


I agree, a little extra money on a higher octane is safe.
