Lower the weight to that of a 4th gen and the LFX with the right gears is a 13.5-13.7s car easy.

Do you have a link to a LFX curve? I tried searching but can't find one.
Here's a LS1 curve:

That's great that the LFX makes 250tq at lower rpm, but the LS1 belts out 325tq at 1800.
Now, when we introduce E/T's, do we also want to consider trap speed? If so, you're going to see several mph lower with the LFX simply due to the lower power.
As an FYI, I'm not trying to infer the LFX is an inferior engine. I'm only speaking in the context of racing against a LS1 in equally-bodied vehicles.
