71 340 manifolds

Those guys glommed that from the bogus list that's been floating around the internet forever. Find a 3418623 manifold in a 69 parts book, you won't because it hadn't been produced. They updated their list to the correct numbers I posted in my thread.

That original mymopar list is as bad as the rear axle length chart that's just as bad with 62-70 B body being the same or A body 8.75's at 51.40/ Both number are wrong for the covered years.
