Well, I just pulled it apart, and the timing marks are a half a tooth off. Either way I turn them, I cant get the dots to line up correctly. This thing never had any more than 3-4 inches of vacuum at idle, even before the timing set and intake swap. Could there be a problem with the cam itself, considering MP's reputation of poor quality products within the past few years? This was a used cam that I got from a friend of mine that "said" he kept all of the lifters in line with their respective lobes
