The 01 has a LS6 intake, a 16.8 gallon fuel tank (the 98's is 15.5,) and no EGR system. It has a slightly smaller camshaft than the '98. The exhaust manifolds are better than the '98s.
The '98 has an actual working temp gauge, the '01s is more of a dummy gauge. The '98 has a smaller throttle body cam. The '98 doesn't have the infamous "black box." '98s also have a different PCM from the other years.
There's a small chance that the '01 might have a LS6 block, but chances are it doesn't. If it's a manual, the 01 has a Z06 clutch.

Other differences:
* There were different colors available in different years.
* There were different option packages available in different years.
-- ex:
-- The 75th aniversary package was availble on 2001
-- Collector's Edition was avilable in 2002
-- 1998-2000: WS6 and Firehawk were both available on Formula and T/A
-- 2001-2002: WS6 was available on T/A only, Firehawk was available on both
* The interior color of 1998-2000 was Graphite (Dark Grey). The interior color of 2001-2000 was Ebony (black)
* The radio also changed.
-- ex:
-- 500 watt monsoon became the standard radio in Formula and T/A in 2001.
-- 1998-2000 CD player headunit cannot control the factor CD Changer or accept AUX input. (The Cassette player can)
-- 2000? CD Player headunit can control the factor CD Changer or one AUX input (this is a bit unclear, I'm not quite sure)
-- 2001-2002 CD player headunit can control the factor CD Changer and other (more than one) AUX inputs
* The available wheels also are different based on year

The "black box" is built into the air bag controller (BCM). It should be the same from 1998-2002.

'98 F-bodies don't have the "black box".

no they dont matter 
maybe, just maybe i have a 02 for some weird reason... i found the #s for the ls6 block, going to look for that in a few, and guess ill have to find the VIN decod thread, if one so exists.

From what I remember reading, somewhere around 35% of all 01 LS1 cars got the ls6 block. My 01 Formula had the LS6 block in the first motor, I then had it replaced under warranty and got a LS6 block again ( I checked the part number before it got installed in the car.)
