I had the same problem with my build last week. I degreed the cam and it was saying 114.5 degrees on the intake centerline to TDC. I modified the cam gear and finally ended with 101 degrees. However, the dots never lined up to begin with and they DEFINITELY don't line up now, but all the timing events are correct by the degree wheel. I can tell you that even though degreeing it was a pain, I think the end result was much more confidence inspiring. |

The most common stock grind is 244° intake duration, 244° exhaust duration, 26° overlap, 0.414" lift. These are all "advertised" figures, not "at 50" figures. He wants to charge you to make an item that should have come with the cam...? Um, no.

thats why i grabbed the cam, said ill be back, and gave him a wink, and shook my head walking out, he knows he lost a customer, i went to him for all my chevy stuff. any idea how to get advertised out of the numbers he gave me, or .050 numbers from any of the advertised numbers you have> |

Stick the cam in the block, get a degree wheel, a dial gauge, a magnetic mount for the dial gauge, and a pad of paper and a pencil, and map it out. Tedious, but about the only way you can map the cam events. |

See this list of factory SL6 cams for the advertised durations. The ".260" is lift at the lifter, that is .390 lift advertised. (1.5 rocker arm ratio) DD http://www.dutra.org/dutraorg/pictures/ ... -specs.jpg |

i figured .390 for total lift, if these rockers really roll a 1.5. is that a good stock cam figure, that link only had advertised duration, no lift numbers. im in the process of getting a nice set of dial indicator and mag base, im either thinking starrett or brown and sharpe. every time i have done degree'ing was at my buddies shop and i used his harbor freight crap. which works perfectly fine but, when i buy my own $#!+, it will be good stuff. |
