found my cam specs, 214,224 duration@.050, 108 intake lobe center, .503 int/.528 exh, 292/302 duration. this cam makes the 15" of vacuum I need but barely. I know this is not a big cam for a bbc but you can definately hear that it has a cam in it. I guess I need something that sounds a little more stockish, that is why I am leaning towards the ls5.
