    Question Shorty header Street cam besides CheaTR cam?

    I'm looking for a cam with overlap in the -4 to -9 degree range that will work good with stock heads and shorty headers, this is my DD and normally see's 2-4k rpm and a couple time a day see's 6k. I'm not looking for a completely stealth cam, I'd still like to hear it a little bit.

    Maybe something in the range of a 220/228 115 lsa...?

    I look forward to your experienced input.

    Thanks!

    This guy with longtubes put down some good numbers with a 222/228 115lsa I tried to find his old video but pm him he can send one to you. I think it was 380ish.

    the second cam looks like the slp cam just with a 113 instead of a 115, number from a local with long tubes was 370ish been awhile don't remember the exact number.

    checkout ebay, do a search for > LS1 cam (fresh copy). the guy does regrind cams and sells them for $125 +$19 shipping.
    he has GM hot cam grinds avalable with your choice of 112, 114, or 116lsa....... I just ordered my second cam from him and was very happy with the first onr, just wanted to go bigger.

    I think with what you want to do you'd be happy and Calli legal with the larger Hot cam on a 114lsa and going through him you'll save some coin

    Well a 224/224 cam on a 114 is -8 overlap same as your second cam but I think the 224 will make morepower in most instances...........

    I'm pretty sure that a 224/224 114 lsa is -4.00 Degrees of Overlap, but I could be wrong.

    So you think this cam will work better with shorty headers than a 222-228, or 224-228 on a 114 lsa?

    I know someonbe who has a224 cam and stock exhaust manifolds and passed smog put the cheap ass has not gotten a tune so I don't know the numbers. I can't imagine that would be the best cam especially since it can't breathe with shorties.

    Overlap formula:

    Add the intake and exhaust durations
    Divide the results by 4
    Subtract the LSA
    Multiply the results by 2

    or

    Add IVO + EVC if you know it.....

    224+224 = 448
    448 divided by 4 = 112
    112 - 114 = -2
    2x -2 = -4

    You are right. Apparently math and Heinekin is not a good mix for me
