Intake Manafold
 

What would be the best intake manafold for a 420HP? I had a Dart Intake manafold but it was for an engine that had a higher RPM range then the 420HP. The max RPM I have is 5000. Thanks

for the absolute best contact wilson manifolds, tell him what your looking to do hell tune a manifold to your needs.

I would recomend a Edelbrock Performer RPM.

How would an Edelbrock Performer RPM hold up in marine conditions? I was told Dart makes some with Merlin Brass coated water jackets.

If it's fresh water you will be alright. Salt water of course will take it's toll without fresh water flushing. That intake being a raised runner dual plane will give you the best torque curve for you combination. A upgrade camshaft grind will also help.

The Merlins on my 420's work great.
