560 SEL kompressor???

[cgoodwin]

Thinking about putting a supercharger in my 1989 560 SEL and I need some advice, preferrably advice from experience...

I have found a Vortec Supercharger designed for a Chevy 350 which is 5.7 liters and the 560 is 5.6 so it should be a close match. What I do not know is:

1) What kind of "waste gate" do I need, where do I get it and how is it plumbed?

2) Does anyone know where I can find a pulley to drive the charger?

3) What kind of ignition control or additional injection will I need to prevent detonation?

4) What kind of mods do I need to make to allow for more fuel delivery?

Thank you,

Chris
