I can run it on strait E85 but we would be in the 630-640 range.
The misconception I am seeing in this conversation is people are relating boost with cylinder pressure, which higher numbers doesn't mean higher combustion pressure. The type of fuel and timing figure into that.
That being said - my tuner would have had no problem pushing my car into the 12lb area (and probably close to 800hp) on a stock LT1 had I had headers on the car. We were pulleyed for 14lbs with the stock manifolds and were making 745wheel at 5700rpm, but without the headers he was thinking the cylinder pressure was going to get us into DET issues. We may be going down that road mid-summer with headers and pulleys for 12lbs and try to hit 800hp on a stock LT1.

Thats weird. Alky injection should give you more power than e alone. When others have added alky injection to e85 they have gained substantially. Did I misunderstsnd your post?
I am going through something similar on my other LT1 build right now. Because it's my daily driver, I am trying to decide if I add blower and fuel and call it a day around 600whp (93 at 8psi)...or, do I add the cam (cant help it, every time I get in the Camaro, the sound of the cam makes me smile). If I add the cam, I can easily run 700whp. I didn't choose the cam for power purposes...I chose the cam because when my car is running it sounds bad ass.
I am leaning toward the Super Street Brawler.
Btw @Ted Jannetty, that can sounds amazing in your video.
