Doh! I confused the Daytona with the Cheeta.
And I left the 'l' out of Belvedere.... still not sure if that's spelled correctly.

I blame it all on old age.

I did a search for the Cheeta & found this:
The Bill Thomas Cheetah was an American sports car designed and engineered entirely with American components, and built from 1963 to 1966 by Chevrolet performance tuner Bill Thomas. It was developed as a competitor to Carroll Shelby 's Cobra.
