Best 454 chev intake for jet boat

[biggraypig]

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.

Both will work but its all about your engine combo.

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...:D

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.
