I have a similar set up as yours except I have slightly worked stock heads (does not matter much, they are garbage anyway) and an Edelbrock performer intake. I make about 11 psi with my BD11-A.
My engine is also 10 to 1.
I pulled a particular LS1 car that I know by about 3 cars from a roll in just 3rd gear. He runs high 12's at 108-109.

You can make a bit over 300 at the wheels with your set-up, but it really depends on the tune. Blower cars can be real dogs if they are not tuned right.
