Sorry Jared, you will not notice a differance in tone by blocking. You will have a more stable bridge that holds tune better. Bill Callaham makes some fine aftermarket bridges for the Strat but I am not sure you will notice a big differance in tone with them. My old Strat has been blocked for 57 years. If Strats were better with a blocked trem then Fender would not have discontinued the hard tail.
Mine was blocked because the old style 3 spring trem didn't work very well.
