    Looking to upgrade my intake.
    What is the best intake for an Indmar 454 chev. 350hp to 390hp. 20.5' heavier jet boat used as a lake boat.

    The Performer RPM will work nice on your fairly stock setup. They will also work well if you plan on more up grades down the road.

    I agree, go with the Edelbrock RPM air gap manifold...

    Edelbrock Victor 454-R or Air Gap, depending on heads you have (990's?) Victor will work best if you have any port work done otherwise you can't beat the Air Gap from Edelbrock.

    I also say Air Gap as well. That's what I've got on my motor...badass intake.

    I'm thinking the performer is your best bet for a heavy boat with a stock motor.Thr rpm manifold is a tad to much.
