Re: supercharging a 408 windsor
You'll probably need to look at things like compression/cam specs/ignition etc before you just bolt a blower on. A genuine 550hp small block is a pretty stout piece, so I bet you'll need to make some changes. I'm using a YS Vortech on my 398 Windsor, and I'm happy with it.
