Be careful

Response to OH the options!
9.5:1 is pretty high, especially for a non-vortec..what happens if you can't get 90 octane? Effective compression is determined by both the cam and the carb. At 4000 rpms with a mild cam and a 4 bbl., you will be filling the cylinders and have high effective compression. It's your boat, but just be careful and do your homework. A little low compression, you may lose a couple horsepower. A little too high, you may lose the engine. Again.
