Its a question of manners.
If you are talking about an outdrive boat you need a decent idle quality or you'll beat up the clutch and gears just getting out of the marina.
The 600 HP through 3 inch open pipes at 6500 RPM is a different proposition that 600HP through wet marine exhaust.
just as important as the 600 HP is what the torque curve looks like. If it cant be stabilized on a dyno below 3000 RPM its not going to come on plane real easy either.
High 600's - yeah not without a blower or be prepared to drop monumental coin on a small block to do this that works in an outdrive boat.
This can be done- but it will be expensive to do it well and by the time you are done a mild big block would have been cheaper.
This is a path Ive personally taken so I know.

Has anyone built a big cube small block for marine use? Just kind of curious, back when I was into cars there were some guys building 427-454 cube small blocks with pretty serious tq and hp #'s. I know they were pretty pricey to build, but in a small boat would the weight savings be worth the cost?
