I am just curious when Ford started using the Super Duty name. As a side note, Pontiac also used the Super Duty designation on their top-of-line 455 engine in the 1973-74 Formula and Trans Am.

The latest was 1999 model year to present. In the mid to later 90's the 450 was called F Super Duty. It was also used in the 60's I believe.

 

1960 was the first use for the super duty name by Ford.

 

Pontiac started using super duty name in 1961 the SD 421 was really something.

 

Pontiac Super Duty was used in the early 1960's....

I remember when I was a kid (I'm 52 now) seeing 60's models of Ford Super Duty dump trucks.

a friend in high school had a Grand Prix... with a 421... and the special wheels.. I forget the year of the GP. high school was 1968 to 72.

 

My second Pontiac (74 Grandville) was a Wide Track, with RTS (Radial tuned Suspension). I'm thinking it was a 454; prior to my current 6.7 PS it was the most powerful (measure by the seat feel) vehicle I ever owned.
