In 1970, I bought a new 340 Duster off the showroom floor. Couldn't figure out why it was so much faster than other 340 Dusters until two years later when I put a 440 in it. My Duster had the 340 sixpack (from the AAR Cuda) motor with a 4 barrel intake and carb on it.
When I talked to the guy at Ford SVT, he told me the first days production were monitored, tweaked and inspected by the SVT Engineers. He also said mine was used for journalistic evaluations.
