Just a thought, here, but if the motor is in fact a marine application, the camshaft specs are probably not to your liking. The motor will run like stink up to about 4,000 rpm, then will fall on it's face. If you are runing A/T, that's maybe acceptable, but standards like more top end on occasion. Or at least that has been my past experience; otherwise, the setup should be really good.
Best,
