Marine Intake is on and running.

[lwrs10]

I am just curious because I have seen yall talk about this "marine" intake in a couple threads. What makes this intake different/better/more sought after? I know very little about chevy engines/intakes.

The stock Vortec 5.7 has the injectors under the upper plenum. People call them the poppit or spider style injectors. Not only are they not upgradeable, they create a pretty big restriction in airflow. they are right in the intake runner paths on a few runners.

The marine one is open on the inside, since it uses normal style injectors mounted on the outside with normal fuel rails.
