Interesting Jim, never thought of this being a 6 cyl cap. According to Bob Mannel's excellent SBF book the elbow nipple is correct for closed emission non-HiPo V8s in 65 and 66, but doesn't go into much detail for 67. I guess that could make the early GT350 and closed emission HiPo caps a chromed version of the 6 cyl. closed emission cap with this particular one being a 67 unit because of the block FoMoCo stamp?
