Doug, in order to do the conversion right, you may have to use the proper camshaft. My guess is that the 300s that came with the dual carb setup had larger cams. If I am correct, using miss-matched parts might deteriorate performance. Before you consider converting your engine to the higher power output, ask yourself if this is what you rally want. If you like to drive your car fast, it may be worth sacrificing some low end torque for high speed. If you like to rev the gears all the way to 4500 or 5000 rpm, and if you enjoy occasional over 100 mph driving, the dual carb is for you. If you don't care for the above, don't bother.
