Do you know the cam specs of your engine? What heads and intake? If you are running a milder cam and some smaller heads, the supercharger is going to definitely get you over the 400hp mark, but with poor flowing heads and intake coupled with the wrong cam, it definitely wouldn't be optimal! If youre heads and intake are already constricting airflow on the 351, it's going to be just as constrictive if you are force feeding it.
