To clarify again:
I was saying that I didn't think there was a difference between the "hand assembly" of the Mustang Cobra motors at Romeo engine plant and the traditional assembly line approach for the Contour SVT engine. On the Cobra assembly line, there are two guys who follow each motor down the line.

I have no problem saying *your* hand built engines are different. But you *specifically* mentioned the Mustang Cobra motors and inferred that they were better because they are "hand built" To me it's just two guys following it down the line doing the assembly operations vs. 1 very experienced person at each station.
