    LS-9 Cam

    I see some of the LS-3 crowd using the LS-9 cam in motors that are not S/C. Plus some local guys where I am at say they are a good swap and are fairly cheap new. Any advice or opinions. I have an '05 LS-6. I am just trying to get some info.

    You will gain with the LS9 cam for it has similar lift but more duration, and later you can hit it with a blower and enjoy it even more, HOWEVER, if you want wow cam and a maggie go with the GT9 from LPE. Its sick and sounds like stock with a little more tone

    Square port heads want a cam with less overlap.

    I have a LS9 cam in my car with PRC .650 lift valve springs. My buddy has the same in his vette. Look up camminc5 on YouTube. He has kooks and Corsa.

    I thought about putting the LS9 cam in my 408, but decided to just reuse my stock LS6 cam instead.

    LS-9 has a nice little lope. Nothing radical, just enough to know it aint stock!

    Re: LS-9 Cam

    GM hotcam is better choice for cathedral port heads. It will create more dynamic compression and get you better power under the curve: 219/228@.50 .525/.525 lift 112 LSA

    The LS-9 cam has a much wider LSA-- I think 122.5. Not a good choice for an NA LS-6 motor.

    Re: LS-9 Cam

    the 122 is for FI, the larger the LSA the more air is forced in the chamber and not out the exhaust..

    The LS6 cam has a 116 so i see a benefit where they can add a SC later on and not have to change the cam...
