62 granatelli Plymouth at flying mile

yup, that's the car! The forum post was written by his son, Jim harris Jr. Jim Sr was a helluva Mopar guy. He bought a 68 Hemi GTX convert new, once. He also had a (60ish)Ghia made Imperial limousine which was once owned by one of the Dodge Bros wives. He had several 70 300 Hurst cars, and a gorgeous red convert '58 d500(?).
Thanks for the help! I'll keep looking for the story about the flying mile at Daytona Beach.
