    302 timing question

    Hey guys, I'm having a little trouble getting my timing dialed in.
    I did have it set once where it would break free from a standstill but now it's just bogging down then going and I can't seem to find that sweet spot again. I've been everywhere from 5 BDC to 40 BDC and it runs best between 25-35 BDC. But I'm not sure where it should be with this cam, Any ideas?

    The cam is a Crower 15512
    from website-
    PERFORMANCE LEVEL 2 - Most popular Ford hyd roller grind, blows
    away Chevrolets. Heavy mid-range.

    It is currently at 29 BDC at idle which goes up to about 35+ BDC when revved. But it is still bogging on take off? Any lower than 25 BDC and it starts to run like crap and runs better in the 35 - 40 BDC when revving range? Is this too much or normal with this cam?
