The hp rating never changed on an ls1 from 98-02.

um yes they did. from 305 to 310, and 320 to 325.

while the 98-00 cams may have been "bigger" then, 01-02's had a smaller duration which made up for the increased lift and valve overlap that the 98+ had.

01+ also had better flowing heads, and some got the LS6 block and oil pumps so it was better all around. 01-02's dynoed higher
