More exhaust manifolds

I apologize, this has been more involved than I intended.

Ok, so based on the above, A-Bodies in 1974 with the 360 HP had a driver side manifold with a large outlet because the DS manifold referenced in the pictures and link is the same manifold that the 1974 360 Duster/Dart Sport came with.

This disagrees with part of the following post IF it is applied to a 1974 A-Body:

I understand that other bodies styles came with other manifolds, and that the A-Body 360 HP came with a small outlet passenger side manifold, but I am only talking about the 1974 A-Body driver side HP manifold, which is the same as the 70's 340 driver side manifold referenced above.

OoooHHH!! I think I understand what your asking about now?? Your concern was with the 360 HP manifold mentioned earlier?? I went back re-read TF360's post. There's where the confusion comes in..... (terminology). When I talk about a 360 magnum manifold I'm talking about the 360 CI magnum engine which may or may not be 360HP manifolds mentioned earlier. We may be talking about two different things here but I am patient and I don't mind writing until we're both on the same page.

When "TF360" wrote:
"Looks good-Do you know if the factory 1974 360 hp mainifolds ( a-body) have the 2 1/4 outlet on the drivers side. They should be the same as the 73 340 drivers side manifolds. Or do only the earlier 340 manifolds have that 2 1/4 hole (drivers side) "

If "TF360" was talking about a '74 340 manifold then yes it could be the 2 1/4" hole. You see, the 360 engine went into production in '71, so when "TF360" asked about "1974 360 HP manifolds" I naturally thought he was asking about the manifolds that came on a high perf '74 360 engine. If TF360 had said, "'74 HP 340 manifolds" my answer would have been different. But that not what he wrote. So I guess it's my fault for not realizing that he was asking about 340 manifold?? In '74 there were 360 engines but they did not come with large hole manifolds BUT SOME 340CI '74 engines did come with the large hole manifolds. When someone writes "360HP manifolds" I automatically think of high perf 360 engine manifolds. But if someone asks about 340 exhaust manifolds, that's a totally different thing.
So yes a '74 340 engine diver's manifold could more than likely be a large hole manifold. Now if "TF360" would come back to this thread and clarify what he meant by '74 360HP manifolds we'll all be on the same page.
Sorry about the confusion.
