Should I supercharge the barracuda?

I've thinking about putting a paxton supercharger on the 340 thats in the notchback. The 340 engine is .030 over and 10-1 with the current J heads. I have new set of Indy TA heads with roller rockers that should produce the same comperssion but flow a lot better. The cam in motor is a 274/451, which might be alittle small but I don't really what to swap it out. The 340 should be near 300hp currently, and mybe 450 with the paxton? I like the idea of supercharging the barracuda, but I have no experience with superchargers.
Any one put a supercharger on a similar engine?
What's the good and bad on superchargering a stock motor to this hp level?
Any good supercharger forms to check out to help with the decision?
So what do you think, superchager it or not?
