Lets discuss another engine build

It's a gain I don't think you'll feel. But it is a gain. Also, what the raw numbers do not tell you is how the engine likes the proper balance so much better. The efficiency and smoothness of the engine will pick up. The engine will feel better on acceleration.

I would yield at 9.5-1 as a MAX! The cam is still small and the octane available to you @ 93 non ethenol is nice but still has its limits. I'm sure someone here is going to chime in and say, "Hey I ran XX.x - 1 ratio and got away with it!" But let's be reasonable and smart about matters. Not greedy and stupid.
