How much HP does a Stock 2001 WS6 have ? I have had my 2001 WS6 for going on 9 years now, and am still unsure of the ACTUAL HP my car has ( Stock )
I have heard 320 HP
I have heard 325 HP
Just curious
Thank you

Flywheel 325 maybe, depending on transmission and years on the vehicle/engine condition.
Rear wheel HP you are actually looking at anywhere in the 275 to 300rwhp range, depending on transmission. The autos will be on the lower end pushing the 275 rwhp mark.

Every LS1 engine built from 1997-2004 has 345-350hp stock. That's a flywheel/flexplate number though, not RWHP (rear wheel horsepower.)
The GM "rated" number for your 2001 WS6 was 325hp (vs. 350hp for C5.) This is a game that GM played with the ratings, wanting C5s to appear to have more power stock. However many stock dyno results have proven time and again that the power difference between a C5 and LS1 F-body is marginal or generally non-existent. In fact, there was absolutely zero engine difference between your 2001 WS6 and a 2001 C5 (both used the revised LQ4/9 truck cam, plus the new LS6 intake.) The only areas that were different were the factory exhaust and induction, but that does not result in a loss of 25hp for the WS6 car.
So to summarize:
Your 2001 WS6 was factory rated at 325hp.
Your 2001 WS6 has an actual engine horsepower of ~350, same as the LS1 in a C5.

Great Information
Thank you everyone for posting
My WS6 is an Automatic ..... if that changes the " Actual " HP by much ?
And now knowing that it has 350 HP vs what GM stated it had at only having 325 HP , is awesome to know

the auto eats a lot of that 350 that it is supposed to have. Personally I don't deal in guesses as each car differs based on its history. Use the search function and you will find plenty of stock ls1 dynos on here. A stock manual flywheel HP may be at 350, but to get that number in RWHP from an auto you will need at a bare minimum of headers, CAI, lid, minor bolt ons, and a tune.

I'm definitely leaning towards getting this 01 WS6 6spd. , and selling my 01 WS6 Auto
I haven't had a 6 spd. car in almost 9 years .... Let alone a 6 spd. WS6

Having an auto doesn't change anything about the actual (or "rated") horsepower figure. Auto and manual were both rated the same (both underrated @325) and both use exactly the same engine with exactly the same power (~350hp "actual", same as C5.)
OEMs never rate a car by rwhp, and that number will be a bit different for every example (even when stock.) There is more drivetrain power loss for things such as an auto trans, all wheel drive, independent rear suspension, etc., so when any of those factors are in play for a given platform, you can expect them to dyno a bit lower at the wheels than variants with the same engine but without those other drivetrain power-sappers.
Having said that, there are some vehicles that come with a different factory rating for the manual trans version - such as 5th gen Camaro SS. The manuals were rated higher due to the fact they received a different variant of the Gen IV SBC V8 (an LS3) vs. what was offered in the auto (an L99.) So in that case, the rating is different because the engines are different (not because of the transmission that happens to be bolted to it.)
In the case of 4th gen F-body, there is NO difference between the engine used for a manual or an auto, so both carry the same ratings and the same actual engine horsepower.

A stalled auto will work a 6 speed every which way in a drag race every time.

A automatic with a stock converter is kinda bland to drive but you add a nice high aftermarket converter it is arguably just as fun to drive as a 6 speed.
My car runs 12.2's @ 111 mph in good air with Lt's, converter and a radial..... There is not a 6 speed car that is exhaust and radial only that is going to touch those times.

I have a WS6 with an automatic and a Yank 4000 stall and another WS6 with a 6-speed and 4.10 gears.
The 6-speed is the car I want to take out all the time, only time the auto is good is in traffic or on a long cruise.
You either like manual transmissions or you don't, and the stall is one thing I cannot stand especially in stop and go daily driving is a loose automatic.

Shifting can often be fun, but that's only half the job with a manual. Then you have the other half....
I totally agree. Living within one mile of the most congested city in the entire midwest means there is always traffic. And nothing is more annoying than clutch operation under those conditions.

Yep, the clutch I prefer especially if you get a twin disc set-up. No effort on the pedal and you don't feel like a drone putting the car in "D" and trying to stay awake.
Downshifts and upshifts are more lively especially in the corners.
I know the paddle shifters are here and GM is promoting them in the current ZL-1 and Z06 and maybe manually shifted cars will be history soon, but I am glad these cars can be had with a 6-speed manual.
