I just hope that the engine doesn't require premium fuel
You can bet your a$$ it need's premium fuel. Anything with compression ratio of 10 1/2 to 1 will need it.
Yea I know if it had around 9:1 compression I could get away with low octane fuel as long as the camshaft had a lot of valve overlap therefore reducing cylinder press. It would be hard to get 500HP out of a normally aspirated 9:1 454.
I don't imagine that insurance would be any problem. As far as they know it is still a 330HP 454. [img]/images/graemlins/grin.gif[/img] That boat might not have a maximum HP rating plate on it. From what I understand the coast guard only require for boats that are less than 20ft to have a max HP rating.
