    whoa.. I am not sure if you realize what a huge difference there is in the cams that you posted. First off if you are a stock LS1 engine you are not going to clear .649 lift without at least pistons with valve reliefs. Driveabillity will also be quite a bit more difficult for your tuner to maintain, definatly possible with a good tuner but it will still be rough.

    I am planning on jumping up to something in the .240s duration wise with my next cam and if you cut down that lift to right around .600 then you should be ok.

    I think you could use the 918 beehive springs with the 224/230 cam but wiht the latter I'd use duals definaetely. If the car will see the drag strip and low ETs are your goal go for the 239/242 but if no track then the former should be fun enough with better manners.

    i would agree w/INMY01TA, that anything over 230-ish @ 112 lsa would be ideal. custom grind it to your application and also if you plan to go heads in the future...

    as an M6 you can still retain the factory 3.42 w/o to much cam surge down low...

    what do you guys think about that .650 lift though? i am almost positive that is well over our max lift for a stock internals setup..

    +1 on the springs. the new 918s are rated at a max .620" lift.
    anything over .600 I'd go dual springs because you would be beating the hell out of them.
    plus that high a lift new springs every 20,000 miles max

    ok i called comp cams and they told me that my best bet is to go with .228/.230 and .571/.573 with a 112 lsa. or if i wanted more race type cam go with a .232/.234 .595/.598 and a 112 lsa. what do you guy think of that? i still want to give texas speed a call but it is closed today.

    My experience with Comp is they tend to recommend on the conservative side. Defiantly, keep doing what you are, talk, call, and read everything you can.

    I'm somewhat of a novice at this but, are you planning on swapping out the stock heads as well?

    With the little research I've done, the smaller cam will work well with stock heads and the larger will probably require something aftermarket. Not sure.

    I know your intake is a LS6 which, will work well with the smaller cam, but the larger? I’m not sure about that either.

    And then there’s the throttle body, and the this, and the that and the. . .

    Just food for thought.

    As for bringing air in and out the LS6 should be fine with a stock throttle body ported. The heads should be able to do fine as well (just make sure you have all the proper valvetrain stuff). Not saying you would not do better with a set of Trickflows and a Fast 92, but you can run a pretty aggressive cam. My bigger concern with a bigger cam is the stock bottom end. The main reason being that with a bigger cam you will want to turn more RPMs. Even with my mild cam 226/228 .585/.588 lsa 112 I shift right around 6500-6700. I can only imagine a bigger cam wanting to go higher and the bottom end not liking that.

    its all in what you want out of the car. Its about your goals and driving habits bro. I mean I would def. not go with the first cam that Comp recommended as it is to small for just about any ones taste nowadays. That second one would be a good well rounded cam, it will have specs alot like mine and since you already rev out that motor pretty far your car would love the powerband.

    as for the speculation of the stock heads. You can do a cam only setup and be just fine, it will not hurt you to not get new heads and you can still run the larger cam for now as long as you upgrade your valvetrain. That being said it would be alot better for the setup if you did heads as well. Not only are you stripping it down most of the way anyways you will be spending a cuple hundred bucks to upgrade the stock heads you have now to make them safe for your cam. You can just save up a little longer and pickup a decent set of heads from ws6store.com for around 1100-1200$ and gain a bit more power.

    The power will come either way as you are letting in more air and fuel by opening the valves longer and lifting the valves higher. However with the roughness of stock heads the air will experience some turbulence and your cam just wouldnt be at its full potential.

    I was looking into the ms4 cam there for awhile up untill i started doing my homework on it. the ms4 cam screams at high rpms it just loves the high rpms. the stock bottom end will be fine the valves will clear without flycutting. alot of people dont want that cam as a DD because it starts to pull late in the rpm band.


    As someone once told me bigger isnt always better.

    in short the MS4 puts out big peak numbers but is lacking in the lower rpms which is not something i would want on the street if i wanted the best results.

    deff. take the advise of some of these guys anything around 230 is a good aggressive street cam

    Anybody familiar with this cam from Thunder Racing?

    99-TR230/224-111 Thunder Racing Custom Camshaft
    "Reverse Split" - 230/224 .575/.563 111 LSA 2200-6800 RPM Power Band. Excellent mid-range & high RPM power. Automatic cars require computer tuning and it is recommend for optimum results on manual transmission cars . Due to the fast ramp rate of this camshaft, the use of 1.8 rockers is not recommended.

    that cam has a more duration and lift on the intake. LS1 have an amazing flowintake system from what i understand. Ls1's love there cams to have more duration and lift on the exhaust side
