So as it happened, I got a "in stock" notification from Midway and got a 617 cylinder.... (after many attempts, they sell out in under an hour for some reason)

I also had one backordered through Brownells....

WELL, now I have 2. One is going in that 67, one I don't know.

Would anyone be interested in one, chambered in .327??? The first one I got was an easy fit to the 67.
