1975 duster 360

Has anyone ever seen 340 manifolds on a 360 (from the factory)??? I've never heard of 360 engines fitted with 340 manifolds (from the factory). I know they will work. Is there any documentation on this issue?? Inquiring minds want to know.

some people say they are some people say they're not. I went to a lot of mopar shows Last Summer and every 360 duster I've seen was either not original or was a 74 so I have no way of knowing
