OK, My intake manifold popped (two barrel 8 bolt 4.3). As long as I have to replace it, I would like to explore a few higher HP options. Ebay has a bunch of Throttle body fuel injection manifold for auto use for sale. Could these be used in a marine application? What type of conversion would have to be done( does it need an ECU etc)? How many HP would it buy me??
Consider this: it takes 12-15 more HP just to gain 1mph!

Problem is most 4 barrel auto intakes are designed to make the power in a higher RPM range. You need a performance intake designed for your boat application. If you know your typical 'Wide Open Throttle' rpm range for your motor/boat/propeller combination, I would start with Victor Edelbrock, and see if his company makes something suited to your purpose. You need a 'dual plane', or else a single plane that has long narrow runners for more boost at the lower end.
