LSx Question?

I just wanted to get the forum's opinion on a flat plane LS variant crank engine. I'm a novice when it comes to the inner workings of an engine (lift, cams, valve timing, etc...) and how high HP is gained in an NA motor.

What intrigued me about the flat plane crank is how lively it made the typical lumpy low revving LS powerplant. From what I've researched to this point, you lose low end torque, but you have a wider power band and can access said power quicker because of the rate in which the engine revs. Please correct me if I'm wrong.

Are there any current builds that are using this method? I've searched through the SLC clubhouse and haven't found anything as of yet. What are the Pros/Cons of a build of this nature?
