Thinking about supercharger

-I'm not a fan of that blower. If you have decent flowing heads it will be very hard to spin a bd11a safely and get 9psi on a 416.

-You won't lose throttle response but if your cam and converter aren't built for boost it will be a dog down low.

-Weight isn't a huge deal when you look at potential power gain. If you went from a full iron small block and changed to aluminum heads, intake, timing cover and water pump you'd still be ahead after adding blower, brackets and intercooler.
