The engine was rated at 350 horsepower and 360 torque at the flywheel.
Here's some info that you may find interesting. My SS was a manual 6 speed, with nothing more than a KN intake and a Flowmaster muffler. My Vette coupe is an automatic 4speed. Stock, the Vette was no match for the Camaro 6spd. The LS1 6spds were bad ***.

I've heard that the cam is actually a little milder in the '01 and '02 cars, but I don't know the specs.
As for "dyno'd much higher", I think 5hp was about all of the difference. The cool thing is that the LS6 intake manifold will support a lot more airflow to keep up with the mods you do later.

AFAIK, the F-bodies and 'Vettes shared the same camshafts in their LS1 engines, however if you look at the 'Vettes, they seemed to switch back and forth a couple of years
. The F-bodies on the other hand used the higher lift cam w/LS1 intake, THEN made the switch to lower lift cam w/LS6 intake, and they stayed that way.
FWIW, my '02 dyno'd 289 RWHP / 307 RWTQ, through an automatic with 4.10 gears, on a hot, humid day
. Track #'s are in my sig. I think that's pretty typical for a "lightly modded" LS1 (lid & catback as the only power adders --- actually, the Flowmaster cat-back is a power ROBBER according to some people ).
In general, I refer to the LS1 as 350 HP, because even doing the math on 289 RWHP, that works out to be a 17.5% loss on 350 flywheel HP. M6's have less drivetrain loss, and therefore they typically dyno ~300 or more RWHP

Re: Real HP in the LS1 Camaros?
Those are probably typical timeslips, but I have seen a bone stock to the filter 2002 SS run consistant 12.9'sand heard of a few others. And yes the '01/02 cams were 'smaller' but the different LSA provided more overlap to take advantage of the of the better airflow provided by the intake. Every car is different; it may have only been 5hp that some see, but from what I have seen of the '02 cars thay seem to run stronger than other LS-1's at the track. I have heard (but not seen personally) of them dynoing as high as 310 RWHP.
