Powerwise; different heads and camshaft. Also the LS6 block has better crankcase breathing and the LS6 also has a different PCV setup.

dpends what year ls1....the 01 and 02 LS1 were basically an LS6 minus the cam and heads but some had the LS6 block (not that it makes that much of a difference having the LS6 block) and all had the LS6 intake manifold...theres a write up on here thats a sticky that tells the exact differences...

but not all the 01 and 02's came with the ls6 intake some did but not all. i think like 15% in 01 and like 30% in 02 came with the ls6 intake.. but they all really run about the same no big dif. b/t 99 TA and a 2002 TA they will run the same at the track. but the ls6 had the same CI (cubic inches) BUT came with a dif. camshaft and a dif. intake. bigger TB's,

As far as I knew all 01-02s came w/ the ls6 intake! I think you are getting the 15% & 30% confused w/ how many f-bodies came w/ the ls6 block w/ls1 internals

Yes he is getting a little confused. ALL 01/02 LS1 powered F-bodies came with the LS6 intake. However, 15% of 01's and 30% of 02's came with the LS6 block which you can tell the difference between due to the LS6 block being "dull". Whereas the LS1 block is "shiny" for lack of a better word.
