I need to positively identify my tractor!

...on Thunderbirds, I was talking about the kids TV series of 1965-66. They had these (from a fascinated kid's perspective) big tractors for all sort of jobs, and the noise they made was a beautiful, schlock-a-schlock sound so smooth you had the impression the engine was having fun running... at least in my memory...
I never owned a Ford Thuderbird myself... only my father did many years ago, but it was in the early 70s, so I guess it was a 5th or 6th generation. I remember my father bragging about its 4 barrels and 454 cu.in engine. Big and fast it was !
