Just curious as to what you guys have down with this. I have a friend build a twin turbo build on his Ford small block. Efficiency wise that seems to be a very viable option. (however, SBC for me). After learning of the many points that Roots are bad for (poor efficiency, heating issues) I figured a TT small block would be a good idea, or at the least a Centrifugal supercharger. Hopefully this thread will be a very cool garage tour.
