ATI Procharger is the best overall because it comes with an intercooler, but you can get a good Vortech system uncooled for a bit cheaper. Don't do a Powerdyne, they're garbage.
Ebay has some dirt cheap supercharger setups.

I also hope you're considering your bottom end as you look into getting a SC. Our stock compression doesn't like blowers too well unless you've lowered your compression. You'd be alright running about 6psi for a few thousand miles, but after that your bottom end will show wear...
I'd advise you do a good amount of research before you drop that amount of cash just to tear up your engine...

i wouldnt want to run anymore than 4.5 psi, 6 is a bit much for my summer everyday driver. i am not lookin for a blower though, just a centrifical (cant spell) would do just fine. I was told those with that low of a psi wouldnt harm anything.

A blower is a common term for a supercharger unit... the housing itself. What your referring to is the Root vs Centrifugal issue... Root superchargers do develop more heat, but a centrifugal will still develop a load of heat without an intercooler. For instance, my car runs at a standard or 200-220* on a 70-75 degree day, in traffic it overheats.
On the other hand, running 4.5 psi won't damage anything, but who wants to pay 2 and a half to 3 g's to get as little a power benefit as 4.5 psi?
My suggestion to you would be to do internal mods such as heads and cam rather than forced induction. You'll get more power out of a mild cam and stage 1 or 2 heads than you would with a vortech 4.5 psi supercharger, and you'll be damaging a lot less.

LT1s make good nitrous motors, but then again how would I know 
The thing is with boost its like any other power adder, you get greedy. An LT1 with a solid built low compresion bottom end, set up with some good heads and a well picked blower cam will run great on boost. Nothing new people have been doing it for many years with these cars making some awesome numbers. Course I have seen recently some wicked LT1s with built motor with a ton of boost and a ton of gas on top making in the 900s at the wheels

4.5-6psi would give you maybe 50hp on a stock motor. Not really worth it for all the hassle, etc. You could do heads/cam/longtubes and make more power and be much more reliable.
I wouldn't do a blower unless you can afford a rebuild (and preferrably build the motor beforehand).
That and I would go with a vortech any day of the ATI's. Their kit's for the LT1's require alot of re-engineering. Get rid of all the intake tubing (it will collapse), reshim all the pulleys/brackets to get rid of all the belt misalignment that is there, and get ready to rebuild that blower from the oil that is going to leak I would buy a used vortech unit and throw on a spearco intercooler. The F1 is the first ATI unit I would consider messing with - the previous ones had too many issues (in my opinion of course).
But then, again, I wouldn't bother with a blower on a stock bottom end (unless you can afford to rebuild it)
