174/177 supercharged small block, where to start?

Hot Rod's Pat Ganahl,did a test of all these little blowers in 1984.Landry had a kit,was eventually discontinued.Hard to find,big bucks.Check out the Mod Man manifold for mounting,top end wise.A typical mild small block build ,would bring 80 to 125 hp wise@5 to 7 lbs boost.The fun is the insane torque curve,while being streetable.On Landry,meant Landy ,by the way
