The S7 Twin Turbo was the first one I thought of actually. And the Ford GT is just an absolute monster. That smaller V8 from the Terminator Cobra (the 4.6 version based on the 5.4 in the GT) was one hell of an engine. Very underrated from the factory.

The main point I was trying to make is that the LSx is a very capable power plant, requires less space to do it, and weighs a lot less. The whole displacement argument really is irrelevant since dimensionally the LS is a smaller motor. But I won't doubt the capabilities of Ford engineers with Ford motors. They can deliver some monstrous power, as you illustrated.

I believe the aluminum LS3 only weighs about 20lbs less, so the iron lsx would probably weigh more

420 vs 440 (sans accessories)

Not really since you can come up with a higher displacement mod motor than the 5.0 that is the same exterior size of the coyote and blow away the 6.2 LS3.

This was a power shootout and the compared an engine with a lot more displacement and I hate to be cliche, but there is no replacement for displacement. it is how the LS is making more power
