I know when I raced the 300 class a few years back you have to do extensive mods before you can notice a power gain. Really if your just looking for more top speed try a 14 tooth front sprocket and a 36 tooth rear. A cam isn't really going to do much for you unless you get some head work done. The 300ex's heads are so restricting.
