8.75 Sure Grip help

If u go back to the 50s u will see that Chrysler first Thad the vortex, the suburban and a few other words/ terms that Chevy has now. Also Pontiac had Super Duty long b4 Ford ever thought of it. Kim

When did Pontiac first use Super Duty? Ford first coined the name in 1958 and that particular engine family ran until 1981. It included the 401, 477 and 534 cubic inch gas engines. I've looked for a 534 for better than 30 years. Always wanted to do a rat rod with one. lol
