I don't think they can touch the ls series mod for mod.This is true, but the Old BBs can make some very stout numbers easy. Those old cylinder heads are just very capable..... they just didn't run that hot from the factory.

A BBC will hands down will stomp a LS series engine mod for mod. The only disadvantages the BBC will have is weight and gas mileage. Heck, if you are going to go mod for mod you might be able to fab up a good fuel injection set up that will help in the MPG department. They might even have a better aluminum block set up than the old ZL1s.
BBCs just start off with better cylinder heads in general. 800 HP is pretty easy for a NA BBC, not so much for a LSX.
I didn't say it would run on pump gas, but:
Here you can buy a crate 565 that makes 800 HP on pump gas: http://precisionraceengines.com/featured-products/chevy-454-stroker-turn-key-crate-engine-800-hp
I learned the hard way that those kinds of ads are misleading. They quote GROSS hp, and not SAE hp. I bought a 340hp 302 once. It dynoed 242. Notice their dyno vid? Not very "SAE" looking to me.
Another example is the LS1 engine. It makes over 400hp bone stock according to GROSS hp ratings when tested outside of a vehicle in an engine dyno room.
You asked for an article, I supplied you with one.
Talk do anyone who really races cars and they'll tell you it's pretty easy to make stupid power with a BBC if you know what you are doing. They make power, they can make lots of power, and it'll be easier than with an LS series engine. It's just what a BBC is.
I love the LS series engines, great power and efficient but they were made to be a passenger car engine and fit in a small engine compartment.... BBCs were designed with NASCAR in mind from the get go. Each has their place, but a BBC is just going to make more power because it'll move more air in the end.
I'll grant you that "in the end" it will make more power, I won't argue that. However, without completely re-doing the engine, the LSX series has a lot more to offer "mod for mod", unless you mean "new/fully machined and ported heads". Then of course, he with the deepest pockets will win.
One thing you are dead-on about is the size/weight, which is why I never really looked too much into the BB world.

No doubt the newer cars today can put most of the old "classics" on the trailer. But the love of the old cars is not just for speed, but they had character. They looked different, too. Today's cars almost all look the same and just don't have any real distinction from one another. Besides, half the fun of owning a muscle car back in the day was to continually play with it trying to make if faster and better. You had to get your hands dirty! Today hook up a laptop and make any number of changes. It ain't the same.
