In 1972, you could get a 318 2bbl Rallye as well as a 400 2bbl, both with single exhaust. The hoods did not have engine call-outs like all the 4bbl (& 6bbl) cars did.

I've seen the Broadcast Sheet on the car being discussed - it IS a legit 400 2bbl export Rallye car. Kind of a neat combo all around.

The 2 Six Pack cars do exist... one is red, the other yellow. Both are VERY early production cars built in St. Louis. They are the only 2 known...
