340 Manifold numbers question

Brian,

It's NOT a 340 manifold. No confusion at all. Some of the internet references are wrong, just like the stupid 8.75" rear end length chart for A and B bodies. Don't believe everything on the net.

My data comes from the 1972 Chrysler Parts books which I think is a more authoritative source than some list compiled on the internet or even Galens books (which as noted, have many errors in them).
