Pro System Carbs can make a custom holley carb spec'd for your engine combination. Bolt it on, set the idle, and go.. He set my 396 up with a 780cfm piece and it's awesome. Idles all day and runs 140mph at the track with the nitrous flowing..

There's none better... Mine was cheaper than a box stock piece out of a jegs catalog I believe... money well spent.

If you have the money get a predator, they have adjustable cfm's so you can run it on your motor now. But if you decide to do more work or a forced induction system you can bring it up some.
