I am looking to squeeze some extra mph out of my boat. At it's current setup I am running 65 mph at 5,100 rpm's. I have the Edelbrock RPM cam and intake along with the 750 marine carb. Do you think that a 1" spacer would do anything to help out? I have one sitting on the shelf, and was looking at using it, but if I do, then I will have to modify my hood since there is only about 1/4" clearance now.
Thanks, Dan
