Reply With QuoteMile, if your cam and head upgrades net you 70-80 hp you'll see that extra 300 rpm. Don't know anything about your boat, but a typical 18-19' jet can see as much as 5 mph more top end with this added power.

The more the impellar is cut the high the rpms will be, if the pump is not tight it will also rev out high, also have our rpm gauge checked. Im haveing my impellar cut to a AB or slightly more on the B side, that will put me at about 5000rpms on a slightly built 454. Also i found that my tach needed to be re set.
Good luck
