Green when it comes to superchargers

[chevythunder]

I am looking for basic answers; I own a 1967 Cobra replicar with a 509 ci.

1. I wanted to know what engine specs were needed to run one? comp. ratio,

2. Which makers are better than others?

3. Which have low profile because I am not sure the clearence I have. I will measure it this weekend.

This is an initial look into so any information would be appreciated.
