Not really, just cheaper and maybe easier to get the same or almost the same power as the average 'decent' hybrids.
There is one thing to say for a basic hybrid. With very little money, no valve changing, only the basics; you can do it extremely cheap and it will outperform even a well modded 2.5L. However, the straight 3L swap with SVT cams will net you more power than the really cheap hybrid.
