LT1, first off, since your post has seemingly turned into a debate over what is faster, may I suggest you try the search feature. i know I've seen this question anmswered a few times in the few months I've been here. Not trying to be a search nazi, just trying to help answer your question is the quickest manor possible.
As for the which is faster debate, I'm sure stock for stock, the SVT is faster in a straight line. In an Autocross, I'm not sure. i don't know a lot about it myself and have never done it, but it seems to me more torque at lower rpms would be an advantage there, and the SVT's extra weight would most likely come from having almost every option standard. All the luxo stuff adds up. Just a guess.
