I had an engine builder mention to me about some airbox mods for improved performance. I have an 85 Johnson 150 crossflow. I'm in the process of polishing and porting an intake and reed blocks for my engine. Has anyone heard of this and if so what or how is this done? If anyone has any ideas on this, please reply and email me at my work address at bmurray@hydromat.com<br /><br />thanks, Bob
