Difference Between 97 and 01 LS1
I was just wondering what GM did in the 2001 LS1 to get the extra power out of it? I was also wondered what I could do to get my '98 Convertible up to the 2001 specs. Thanks :D

The main differences are the 2001 has a different cam and the LS6 intake manifold. There really is not a big difference between the two cams, the 2001 has slightly more lift with slightly less duration than the 97 cam. If you want more power you are better off going to a good after market cam along with the LS6 intake. Switching to the 2001 cam is not worth the trouble and expense.

I agree might as well get a "real" cam in that beast make a healthy improvement not just a step up to a 2001 spec.
