    228r cam?

    never done any sorts of cam work but ive done some research and wanted to see what you guys thought of this set up

    02 z m6
    228/228 .588, 112 lsa, tungsten pushrods, .600 lift valve springs, ported ls6 oil pump, ls2 timing chain, headers and a tune?

    was also wondering if the timing chain upgrade is needed? and or if you have any suggestions thanks!

    i would go .650" lift (dual) valve springs...IE: Patriot Dual Gold Valve Springs .650" lift.

    you should be fine at the stock pushrod length of 7.4", but double check. im running a 224 single pattern cam, same lift (.588), same LSA (112) and im running Comp Poly 7.4" PRs.


    the 228 is a proven under the curve cam, with good tuning and street manners. you will be pleased

    I put down 418 with patriot 243's and a fast 102. I need a bigger cam for my set up (which I am looking into) but I think your gonna be in the 380 area with out heads.

    Yes the old gears work fine w/ the new chain. Just inspect the teeth and make sure they are in good shape. The ls2 chain is much beefier, great inexpensive upgrade/insurance.

    Yea it will work. You might as well buy it because you will have the oil pump off anyway.
