The big differences in the 98-00 LS-1's and the 01-02's are the cam and the intake. The intake is what is called the "LS6 intake: which is the same as what is on the 02 Z06's (LS6 engine). It is a little better flowing and frequently shows about 8-10 RWHP on the dyno.
The cam though is actually a little less aggressive. The reason this was done was that the SS's/WS6's/Hawk's were putting out about 335 HP (advertised at the flywheel). If the more aggressive cam was kept in, it would have meant HP numbers that would encroach of those of the Vettes (345 HP) which ofcourse is the GM flagship car. So they were cut back slightly even though anyone can tell you they are still underated (personally = 335 RWHP 350 LB/Ft RW Tourque with nothing other than lid and cutout). That equates to about 385 HP at the flywheel.
Hope that helps a little.
As for the racing aspect between A4's and M6's:
A4's are MUCH easier to launch. You can preload the rear which helps control spinning cause you dont shock the rearend like you would with an M6 when you drop the clutch. ANd you only have to worry about the gas pedal as in if you spin, you can play/feather the gas. With a M6, you have to feather the clutch and play with the gas to find the happy medium that day. Also, an A4 shifts alot quicker than even a great Manual driver. In additon, an A4 will only shift 2x's (1 to 2, and 2 to 3rd) while a M6 driver with stock set up (3.42 gears) will have to shift 3 x's in the 1/4 mile and still has the chance of a bad/slow shift especially between 2nd and 3rd while the A4 is errorless.
Like SlowLS1 said, on the street, a M6 has the advantage. This is due to more gears (5 foward gears compared to 3 in an A4 - not including OD in either) which allow the M6 to select a gear that puts them in the high RPM/high HP range when an A4 has to use what the computer gives him. An example is that a 60mph - I can drop to 2nd gear which puts me at about 4000 RPM and in an high HP range. In additon, the M6's tend to put out more HP (to the rear wheels) and have a better gear in them (3.42's compared to 3.23's) which helps with pulling power on the roll.
Hope this clarify's some things.
