When your trying to compare a stout engine engineered for boost against an N/A engine with a blower slapped on, the comparison will get ugly.

But If your talking about a stock GT500 compared to a blown LS3, then that's different.
Agreed, that 5.4 LOVES boost. Now, I would like to see a blown LS3 with a fully forged bottom end vs. upgraded blower GT500. Hey I can dream right...
