The landy supercharger is a 174, so it's more compact than say a 6-71. The manifold is a custom piece. They have different pulleys to tailor the boost output to the AMC V8 and compression ratio's of the motor it's installed on. The kit also comes with a 10 Rib V-belt. They said that camshaft choice is also important to how much boost and compression you can run. They will also polish the blower for a fee. It boost output 45% over the same combo without the supercharger but smaller pulleys can do more. ============================================================= Posted by wixList Archiver -- http://www.amxfiles.com/wixlist
