No 351C manufactured from August 1969 through mid 1974 was ever equipped by Ford with a "smog pump" (Ford's actual name for the pump was a thermactor air pump). Not in Mustangs, Cougars, Torinos, Montegos or Rancheros. It was not "omitted" from the Pantera. The Cleveland's siblings, the 351M and 400, got pumps in 1975 when catalytic converters were installed in the exhaust system. The exhaust ports in the 2V Cleveland cylinder heads were modified to allow air injection at the exhaust ports beginning that year.
Back to the topic of replacement carburetors.
