    Cam breakin procedure

    Once I have this new cam installed (comp cams 222/224) I would like to know how to break in this cam. I have heard that 20 min at 2000RPM is sufficient. Any thoughts? Thanks

    LSx engines run roller lifetrs, no need to break in the cam, if anything make sure it's coated in engine oil before you install it or cover the lobes with engine assembly lube just help on start up, other than that, no need to do anything else.

    Heat cycling the new valvesprings isn't a bad idea.

    But as mentioned...the cam itself needs no break in.

    if you already had the car tuned, there is no need for a break-in period. they wrapped it up to about 6000rpm or so.

    i have a Comp 224 and no break-in was needed for it...

    Yup no break in, its all roller not flat tap which did require break-in. Its more critical now running stiffer springs to let the engine reach operating temps before hammering on it. Stiffer springs = more brittle the metal

    Question for you guys, I have heard that the new springs need to be warm as stated above, but I am curious as to whether that is everytime the car is turned on you should let the engine heat up to heat the springs or is that supposed to be just the initial start up after springs are installed? Kinda confused on that, different people say different things, hell some say they dont need to heat up at all due to most manufacturers baking them before they sell them.

    Both.

    You want warm springs before going to max RPM's.
    New springs you want to heat them up and then let them cool once. Always make sure you have warm oil up there before spinning it high.

    valve springs these days don't need any heat cycling. the type of steel being used is not the same as he tool steel they used to use years ago.

    now, yes, it's better for the entire engine, mainly cylinder walls, to wait until it's warmed up before beating on it.

    You know...I have heard that several times.
    Still...I think I will heat cycle them once...just to be sure.
    Isn't time consuming or difficult. Piece of mind is all.

    Heat cycle!
    The cam itself don't need break-in since it's a roller cam (Hydraulic roller lifters)
