Just got the car back from Lingenfelter. I got the 650HP SS package - Maggie Heartbeat, Lingenfelter Cam and Heads - along with ARH 1 7/8”x3” headers w/high flow cats and a VCM intake.
Of course 650HP is measured at crank. It dyno'd at 567rwhp and 490 torque. I have a ton of pictures. Lingenfelter posts progressive pictures to a Dropbox account as they go. It was pretty nice to be able to see how it was being built. I had to refrain from putting all of them in this post

.
All in all it was a great experience. They really have a good organization, and are great to work with.
As for the car, I have to echo what I've heard others say after getting a supercharger on their SS - it's like the car was built for it. The extra HP wipes out the feeling you're in a heavy car - it's a great drive.
