I assume then that the column shift in a 68 400 is extremely rare. Also, the 068 cam in the 68 400, not listed as HO, is also extremely rare. I was only curious because I had found the 068 cam when I was expecting to find the 067. And, everyone keeps saying they didn't make column shift AT 400's in 68. Would their be an advantage to using a cam with the same specs as the 068? Or, would you rec going with something closer to the 067?
