WHAT WOULD BE THE MOST POWERFUL COMBINATION, MY STOCK V-6 WITH MODIFICATIONS, OR ONE OF THE FACTORY FUEL INJECTED ENGINES?
Fuel injection is definitely the way of the future, but not because of power increasing capabilities! The fact is, fuel injection itself does NOT add significant horsepower to the engine. The extra power associated with performance fuel-injected outboards comes from the use of higher airflow throttle valve and reed assemblies. The fuel injection allows these modifications to be incorporated without incurring the low rpm bog and throttle response problems that show up with equivalent airflow carburetion systems. Fuel injection is the answer whenever you encounter throttle response, or fuel control problems that cannot be practically handled with carburetion. So, while the fuel injection is nice, either way you will probably want to bolt on things like heads, etc.
