There is quite a bit of confusion on this. Several sources say that GM switched the LS1 to the same block as the LS6 in mid 2001 and that the blocks are the same from that point on. Here are a couple of more threads on the subject that will add to the confusion:

LS1: A319 T5, 107#
Displacement = 5.7 L. / 346 CID
Bore x Stroke = 99mm x 92mm / 3.90" x 3.62"
Compression Ratio = 10.1:1
Horsepower = 345/350 HP @ 5,200 RPM
Torque = 350/375 #-Ft. @ 4,400 RPM
Redline = 6,000 RPM
Fuel Cut OFF = 6,200 RPM.
LS6:
Displacement = 5.7 L. / 346 CID
Bore x Stroke = 99mm x 92mm / 3.90" x 3.62"
Compression Ratio = 10.5:1
Horsepower = 385/405 HP @ 6,000 RPM
Torque = 385/400 #-Ft. @ 4,800 RPM

Hum, after reading all this info I have come to the conclusion that a ls1 can be moded and beefed up as high as a ls6 can as it appears Block displacements are the same. Meaning, I can cam, heads, and exhaust my ls1 and run with ANY ls6.

By the way I showed the machanic these pages and he still argues the differances are so minute there basically the same. Told me I could buy a chip and run with the best of em for thousands less. But I think I ll do my exhaust and start from there.

The point is really that the things that made the LS6 different to the LS1 are all the thing you modify on either the LS1 or LS6 from the get go.
IOW once you swap cam and heads all bets are off. You will normally at a minimum do headers, intake, air filter and tune to go along with the new cam and heads so the LS1/LS6 difference become moot at that point.
Now unless the LS1 owner changes out tyres, wheels, shocks, sway bars and brake pads the new "powerful LS1" car is still going to struggle to run and gun with the C5Z06 anywhere outside of a drag strip or freeway roll on.
And the stopping, turning and acceleration of the C5Z is actually what differentiates it from the C coupe and vert
Stay away for this person.
There is no 'chip to buy' for the LSx stup - they can be tuned, by competent tuners, but there is no 'chip' that is going to do anything meaningful.
