I'm not complaining BUT... I have a 2000 WS6 6 speed. It now has 11k miles
I bought it two years ago from a forum member. He told me he never touched this car. He owned it from about 6k to 9k. for about 3 years or so.
Original owner supposed optioned it out by SLP. So it has SLP Long tubes, high flow cats, and cat back.
But it has a LS1 motorsports lid? not sure why it didn't get a SLP lid.
It had a LS6 intake with EGR fittings.
I just removed the intake and put on a ported FAST 92 intake with a NW 92 TB.
I had it tuned at speed inc and dyno'd.
I've attached my dyno sheet. Everyone is impressed with the results.
I called the second owner yesterday and he confirmed that he didn't do anything and that he did not take the original owner as someone who did much. Original owner was older and it seemed that he just optioned and had someone do the bolt ons.
No obvious cam or head work. Has 241 casted on the heads.
What do you guys think? Just a strong motor because of low miles and good up keep, or a sleeper cam?

The guys at speed said too much for bolt ons. Even though intake ported. If it has a cam how come it peaks hp and torque same place you would expect a stock cam? Shouldn't it peak closer to 6k.
What cam do you guys think?
Any other mod that could have given these types of numbers?
The car has no suspension mods.

it might have a little more than you think. IIRC, 241 heads where only on 01/02 fbodies, so maybe someone ported the heads a bit if they arent original. I wouldnt be surprised if its stock cam with that little mileage though.
Either way nice numbers OP!!

Hp and tq is peaking where it should for a stock cam car so it's not a bigger cam. Unlikely the heads have been worked with a stock cam, so I'm leaning towards the dyno itself

I didn't realize that 241 were only on 01 an 02.
No one says that they hear a cam in the car.
They dyno could be friendly but it wasn't a friendly day- hot and humid.
I have seen 15 hp over ls6 several times. That is why I sent with it. I got lucky with the port job. It was a freebie.

My friend had an 01 WS6. It made close to that with only a few boltons. It was crazy fast with basically nothing done to it.
My dad used to tell me stories how Pontiac would test parts by sneaking them into production vehicles. Who knows. Enjoy it!

I don't see anything wrong with the numbers or the powerband. My old SS had similar power curves. It made 25 less hp through an auto with an LS6 intake. I think it had 17X11's on it at the time as well. Some cars are stronger than others.
