I have a nice set of 6-72 dated exhaust manifolds. My book says 340 and these later carried over to be for 360. $50 for the pair. The casting #'s should be visible in the picture. The Casting dates are 6-7-72 left side and 6-26-72 right side.

Located in Kingston, IL. PM me for details. I will ship at your expense.

3751084
3478823

These look like the casting #'s to me, if I can read the pic.
 
I have a set of 67 small block manifold that dump just like these and so do my 71 manifold. I'll check my book when I get home too see what it says. I'm sure I had these on a Dart Sport once so I know they fit.

3478823 My guess is this one is actually 3418623 which is a 72-73 340 pass side exh manifold.

The drivers side is not an A body 72 340 manifold.

More likely off a 73+ 340-360 other than a body based on the casting dates.
 
ok, crackedback got he # right, it's 3418623 which in my book says RH 91-73 A, B, E 340.

The other is not listed in my book but 3751083 is the closest # and it fits LH 73-74 B, C, E 340 and 360. These two were a matched set on an engine I tore down years ago and the cast date is really close on the two. Now, I have another identical set that I will post pictures of in a minute. One of these I ran on a Dart Sport about 20 years ago. Decide if they will work for you or not, they are both for sale, $50 a set.
 
Here is the second set of manifolds I have for sale. 340 Plot has asked for a set so consider him on the list for one if he chooses.

3418623 is the same as the first set.
3418621 in my book says it fits 1971 B, E 340 and C 360.
Anyone know what the -3 means?
Both sets have moving heat riser valve. If they don't sell here I will list them on the B body site. let me know if your interested.
 
so, which ones will work on a duster? lol i am not a numbers guy.
 
#1084 to 8621 Are spoken for by Steve. The second set I posted is still available. 340plot has dibs on those if he wants them, otherwise I have a third person in line for them. I'd like to get these settled and shipped out by Thursday because I am going away for a long weekend starting Friday and won't be able to ship anything until the following Tuesday.

I'm the original owner of my '72 340 Duster and those don't look like the ones that came on my car. The passenger side is definitely not at all like mine.
 
GT340, your user name is confusing me! Anyway, the numbers and body type these came from are listed above. Only one casting # came back to an A body. The right side in the top set of pics is listed as fitting an A body (at some point). Interestingly , the two sets are identical otherwise.
 
Yup, the right is identical to the two right sides I have and the left is different. I think mine are later, probably for 73 and up since the # carries over for 360's also. These might not even be the same as the later A body cars, I don't know.
