No, they used the term "455HO" that year.  They did not have a beefed up bottom end like the other super duties.  A complete engine is still worth a lot of money, but the block itself was ordinary.

Super Duty was a marketing term used by Pontiac, they certainly didn't consider it suitable, moreso now.
