I'm tearing down my 400 SBC to replace the heads with Vortecs and I was planning on a Comp 280H cam to swap for what I had figured wasn't much of a cam that's in there, but now I'm wondering. The old cam is stamped Z010 on the back (dizzy end), and if I'm measuring correctly it's got like .325 lobe lift (measured with calipers diameter along a lobe, then diamerter 90 degrees away, got ~.500, and ~.175 = .5 - .175 = .325). Can anybody tell me the specs on this? I could only find one post online and the guy there said it's a 292H cam with ~.501 lift which is possible my measurements are kind of rough. Thanks in advance!
