Apparently not. As far as I can tell, they downsized them with the 360 because the 360 had a lower HP rating, since it was made during the fuel crisis years. The 360 manifolds I've seen are 2 5/8" ball connectors, which I think used 2.5 inch pipe?
The numbers on these manifolds for sale are 3418623 passenger, 3751084-1 driver. Guy is asking $100 for the pair.
