You should definatly get the supercharging book and read up before adding one.
But if yer lookin 4 good power without spending a ton, you can get by with a lot more using a smaller roots type (like the Weiand 144 unit).
It will add great looks with around 100-125 horses by just bolting it on.
No need 4 fancy carbs. Get a nice Edelbrock 600-750 or a holley. On the smaller units (1440 you dont need a lot of xtra things.
Even small ports will work but you loose some power over like afr's, but cost is way less.
Im buildin a big 6-71 so let me know if you need help. Cya, HG
