I did't mean for this to happen. I got a good deal on this short block. so I bought it. He told me it had 12.5 to 1 with his 75cc heads. LOL wrong ! and it had small domes on it. so now I am try to do the best I can with what I got.
Your thinking is correct, that if you optimize this combination you will likely be over the limit of a stock block unless you go easy. But going easy is tough to do when you want to see what it can do. Why not take the domes off and rebalance?

Why not put a bigger cam in it, back the timing out a little and rev it to maybe 63-400. That way you're within your comfort zone but will still probably run mid 10's. I shift my .590 at around 6300 with nearly 13.1 comp, trap at 6700 and it's pulling like a train. Mick

The CR is not to high,and its perfect to run E85 and even better to run alcohol.I think you would like the alcohol better than the E85 and it would make a lot more torque,more torque=more power/speed with out having to raise the RPM level.
