Low-End Torque F-body 98-02
I know the cam shrank in 01 to give the car more low-end torque.
I was curious to hear from anyone with personal experience as to how pronounced that is, and if changing the cam would be worth it. I am interested in low-end but I certainly wouldn't want to sacrifice too much high RPM power.
Thanks

dont waste your time with it the difference is tiny. If anything the 01-02 car maybe a tad bit faster although theres no hard proof for this. If you are going to change a cam do something worth while even an ls6 cam is better than any ls1 cam and even that is debatable on whether or not its worth it. Imo the smallest cam for these cars should be a 220/220 ideally a 224/224 or 228/228 are the most street friendly.

Interesting responses so far, anyone have any more info, anyone ever felt both cars? What kind of powerband differences do the cams do.
I do know the 01-02 got the LS6 intake as well, the cam should actually hurt performance slightly because it is milder, but the LS6 intake more than made up for it, and the 01-02 cars are the fastest stock ones generally.
The question is how is below 2.5k, below 2k, below 1.5k etc different on the two?

But, as mentioned, if you are seeking a kick in low-end torque, you will need to consider an aftermarket cam over any factory cam. The LS6 is a top-end cam, the pre-01 cam will not yield any noticeble gains.

MY first Trans Am was a 2000 and I will tell you it was much stronger than my 2001 - stock for stock. The funny thing is, the 2000 was a non-WS6 and the 2001 is a WS6. For whatever reason, the 2000 was just clearly stronger, and had more torque down low. The 2001 seemed to be better up top, which makes sense considering the intake advantages.

the stock gm cams don't allow the heads to reach their flow potential.after market cams have more intense lobes,better lobe quailities.talk to Pat-G he will spec you great cam.

Right now just to let you know, I do have 4.10 gears, intake, pulleys, pro-5.0 shifter, Borla on my 98 T/A. I basically have basic bolt ons and some freebie ones (like the EGR mod, etc).
BTW, does the "Performance Tuning" on a hypertech power programmer worth using?

Ya thats what I was trying to get at was that if there is any difference between the two cars its negligible and not really due to a cam difference. That being said Ive driven BOTH cars countless times even a 2000 also and can say the other years may have felt a tad faster down low but I think it was entirely in my head because as stated a straight up race never lies. Point being is if your doing a cam do it right lol.

Sorry I don't have a good answer, but my '01 SS sure feels good.

"The Z28 and SS models received the intake manifold from the LS6, the engine used in the fifth generation Corvette Z06 from 2001-2004. This change also resulted in a revised camshaft profile and removal of the EGR system."

Thanks for the responses?
Anyone else driven or felt the difference?
Also, what cam would be good to give me a nice wide torque band in my LS1 w/ 4.10s?
I don't mind sacrificing some top-end for low-end torque (I want a daily driver) but I don't want the thing to be a dog up high.
The way I look at it, 12 years later, cam tech. should be able to give me more low-end and maintain or increase top end. I just don't know which grind/brand to get.
BTW, 98 LS1 T/A 4.10, Full exhaust+borla catback (mid headers btw), EGR mod, Ram Air Mod, Pro-5.0 Shifter, dual friction clutch, k&n, underdrive pulleys w/ alternator overdrive.

I dont understand how an aftermarket cam can give more low end torque than a factory cam. Cams trade low end torque for upper rpm horsepower. Can you elaborate on a cam that will show such gains? That would be a great street cam although you would be dissappointed when you dynod less.
