    Can someone tell me, what's the largest Cam?

    With a completely stock 2001 LS1, considering an aftermarket cam, what is the maximum intake/exhaust lift without altering the lower end for piston/valve clearance?

    Would there be issues with the heads and related components?

    Thanks in advance.

    Lift isn't the issue so much as duration.
    And it depends on the grind of the cam as well.

    You shoud stay under a 0.60 lift to be on the safe side. This is what an ASE certified mechanic told me.

    There are cams that have .640 lift and clear the stock pistons.
    It is in the duration.

    I was considering the SLP 'PerformancePac' #28039. The bolt-on package 'claims' 400hp performance which is more than likely, slightly inaccurate. If I installed the 'PerformancePac' I feel as though I'm locked down to any further engine performance enhancements.

    I would like the option to continue if so desired. So, without turning this into a major upper AND lower end performance project, I figured I'd focus on the upper end, possible cam, induction - including possible throttle body and head mods., complete exhaust replacement and necessary bolt-on suspension upgrades. (Don't wish to pull the motor.)

    This is why I inquired about the cam, for a 'Streetable' car.

    I would stay away from SLP when it comes to parts. Unless you are getting their linelock or their airbox lid.
    They bloat their power claims (because they give you flywheel numbers and over-rate the HP gains) and have terrible customer support.

    If I am not mistaken, that 'performance' pac doesn't do anything with internals, so it wouldn't restrict you later.
    But you can find better parts for cheaper from our sponsors.


    For streetable power...I wouldn't be looking for the 'biggest' cam. TSP has a 228R bumpstick that would work perfect.

    Any mods on your car as of right now???

    Absolutely none. Totally factory original.

    if your stock and are wanting h/c set up your gunna need headers for sure and prolly TD's or catback and a fast intake wouldn't hurt the h/c either

    Start with little stuff.
    Subframe connectors are a must. Worth every dime.
    Airbox lid and a quality catback. I recommend the SLP lid and a Magnaflow catback.
    Headers would be next. Budget buy I would go with Pacesetters.

    Before getting into the internals, get all the bolt-ons first, otherwise you won't be taking advantage of the cam and heads potential.

    I suggest you start looking into a new rear end. I reccomend a moser 12 bolt w/4.11's if u got the 6 speed to make full use of the cam.

    The Moser 12 bolt (with Truetrac) goes for approx. $2,300...Yikes! Can't just slap a set of 4:10's in the factory rear and call it a day?

    What would the gains be with the TSP 228R over stock?

    Bolt-ons = 345-350RWHP
    228R with bolt-ons = 400+ RWHP (with tune)

    9" for M6 cars.
    12 bolt for A4 cars.

    The 400+RWHP, does that include a head swap as well?

    Additionally, what's your thoughts on a port and polish on the throttle body?

    Many thanks...

    400RWHP can be reached with the stock heads never being removed.

    With that TSP 228 cam would you need to modify the rockers and springs too?

    With ANY cam you need to upgrade valvesprings.
    Stock rockers can be used though.

    bout what I figured. I know on my jeep new springs were not required. Granted, to get a bigger cam than what comes stock in my '91 we were gonna have to go custom grind. Suckers come with a .272/.272 stock

    Sounds like you should do allot more researching. Sign up on LS1TECH and read the stickies and use the search feature within specific forums. That will keep you busy for awhile and you will be on the right track of understanding of aftermarket modifications. Like KISS, keep it stock stupid. And yes, cam only can blow up your rear like nothing. That expensive part you mention, ya over 2 g's. Being completely stock you could put any easy 10 g's into your car without trying. My car came with the stock heads and cam and had well over 10 g's into but it is set up really nice now if I want to go crazy with it. In which I am doing, good luck and welcome to the expensive world of performance. If you are gonna do it, do it right by the way.
