Cordoba manifolds on 73/74 B

[Montclaire]

Any reason why I can't run a pair of Cordoba or Fury/Monaco 360 manifolds on a 73/74 B-body? It seems like there is a split from 75/76 to 77/78, but I do not know what the difference is. Thanks

I wouldn't think so as the kframe is pretty much identical as well as the placement of the steering gear are the same HOWEVER I don't know for sure as I've never tried it.

What was the last year for duals? I'm wondering if the change in 77 was for the y-pipe. Could also be for emissions.
