More exhaust manifolds

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

The pics in post #47 show a 60s 340 driver and a 70s 340 driver and they both have the large 2 1/4" exit hole....As far the seller in the link....the driver's 340 manifold is the large hole (2 1/4" outlet). If it has those ribs above and below the front part of the manifold and it has a flat flange it's probably a large hole 340 driver (70s).

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:

NO!! The 1974 360 HP manifolds do not have the 2 1/4" outlet. Only the 340s (and only some of them) have the 2 1/4" outlet.

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.
