built a 408 small block. supercharger options?

I have a 71 Dart with an air to air i/c. It'll also have the AIS meth kit. You just have to do some fabbing to get things to fit. Yellowbullet.com is a good spot to find used parts for forced induction set-ups. Your buddy will have a lot easier time than you finding a used setup for his chevy. I have some pics on moparts in the power adder section of my i/c set up.
