Well from what I hear our engines can hold around 400rwhp or so without breaking any. But if you want to run more than 10 psi on a stock block I would suggest upgrading to forged internals that would be best. If you could get an 03/04 block they got forged internals already but going that route will cost a good amount of money.
Blower wise all of them are pretty good just depending on the set-up.
If you get a centrifugal supercharger like Vortech, Paxting, or the Procharger series those do not hit full boost right off the back. They build up boost by rpms.
The Roots style superchargers hit full boost right when you stomp on it.
Eaton, Kenne bell, Edlebrock and Whipple which these bolt on top of the engine and not on the front side.
The one I got is a vortech v2 sq trim which can run up to 20 psi with of course the supporting mods to get it to be able to handle that much.
If I am wrong on something someone feel free to correct me.
