    Best Cam for LS6

    What is the best cam to install for a stock LS6? I want to install a better cam without changing heads, springs or pushrods. I want to be able to drive it on the streets and also the drag strip.
    Its an A4.

    Do you have an A4 or a M6? Changing the cam needs a tune for an A4. I personally would not change a cam out without at the very least getting chromoly pushrods.

    Take a look at TR website: http://www.thunderracing.com/catalog...&vid=7&pcid=51

    I would probably go with one of the ones below since you aren't going to be changing the springs. Going anymore aggressive could warrant problems especially if you are a higher mileage vehicle.

    Your stock valvesprings can barely handle your stock cam.
    If you don't want to swap valvesprings, you shouldn't change your cam.
