    CTS-V and the LS6

    There are a number of ongoing debates about pushrod vs overhead cam engines especially in the Cadillac community.

    Cadillac needed an efficient, lightweight, compact, and powerful engine to propel its newest sedan.

    Choices;
    1. Supercharge the existing 3.6L.
    2. Use a Northstar.
    3. Borrow an LS6 from the Corvette.

    Problems;
    1. The 3.6L is a completely new and expensive engine, any new performance items would be developed from scratch.
    2. The Northstar is an expensive powerplant that is just too big with its overhead cam configuration to fit in the CTS engine bay.
    3. The LS6 is race proven with many existing and relatively cheap off the shelf performance parts.

    If you apply Occam's Razor the choice becomes clearer.

    "If you have two equally likely solutions to a problem, pick the simplest."

    "The explanation requiring the fewest assumptions is most likely to be correct."

    ... or in the only form which takes its own advice...

    "Keep things simple!"

    The LS6 gets the nod.

    Re: CTS-V and the LS6

    i have a question the CTS and V. is the CTS a front wheel drive car and the V a real wheel drive car. but are they both built on the same platform that sounds like a major mod to make it this way or the V is built on a different platform. i thought they were the same car (basically) except for that LS6.
    just need a clarification.

    thanks,
    toms...

    The CTS and CTS-V are both RWD, they share most of the same components, with the V getting the LS6 and suspension hardware to match the increased capabilities.

    I can tell you after owning a Z06 that I look forward to doing the same mods on my CTS-V as my Z06, that should shock some drivers when they pull up next to me.

    Have you tried nitrous with the Z06?

    How can anyone argue the overhead cam thing when you have a 405hp production motor that gets 30mpg????

    Logic and science doesn't necessarily mean anything to the "Me Too" crowd. If Paris Hilton drives a Brand X with overhead cams then I must have one too.

    You know the type.

    Very true. Not saying that one is better than the other, just don't think one is better than the other.
