how is the sc trim

If you do not plan on doing much of anything else an S-Trim would be a little big I think. Don't get me wrong, the S trim is a great blower but I think on a car that has stock heads/cam/intake you are putting your headgaskets at constant risk. I recommend a Paxton NOVI1000. Not just because I have one, but rather, the Paxton kits are a lot nicer. Also, mine as a single belt set up and an adjustable tensioner- the Vortech units do not have these. With an Anderson power Pipe and an Anderson pulley set up I see 11-12lbs of boost. That's more than enough. Vortech units are excellent as well but they are just a tad below the Paxton units in quality....keep in mind that they are owned by the same company. Also, a single belt is not withwout its flaws but it has served me well. The smaller vortech is a reliable unit as well. I guess the answer to your question depends on your future plans.
