Don't do the cc306...there are much better grinds out there. Longtubes, LE2 heads and the xe 224/230 will make over 360hp to the wheels in an automatic car.........362rwhp to be exact in my car with a Vig 2800. Ran 12.26 at full weight on ET streets with 3.23s.
Add some 3.73s and more stall speed and you'll run 11s with a totally streetable package. The 306 would make more peak power but at the expense of low end tq (due to the overlap) and poor driveability as compared to the XE grind.

if you're only shooting for 350hp heads aren't a necessity. Shoot there are guys making 350 rwhp cam only on here. But if you want to step up and make some great power, a heads cam package is where its at. AI, LE, and eric bradby, Joe O setups are very reputable. An aggressive setup, with a good tune and all supporting mods will net you right around 400rwhp. A converter with a 3K+ stall range is required. Just get a good one for good driveability. Also, driveability is personal preference. When we did the cc306 in my buddies car with a 3200 converter it drove just fine for my tastes, with no tune at all. If it had a dyno tune I'm sure it would be more civil. Just know what compromises you're willing to make. Then get it done!

In most instances...but a lot of people's setups are a little out of sync. For instance, I would bet an a4 with a decent converter (3kish) with a gm847, gtp6 or similiar, with rr's, lt's, ory, good tune, and a 12 bolt would top 350rwhp.
