Isn’t it 321 from 77 to Wilkesboro the Junior Johnson HWY?

421. And the real Thunder Road has had most of it’s deliberately built extreme curves taken out of it, still a few. 115 from Statesville.

It's actually 421, which runs up past Wilkesboro through Boone and into Tennessee to Bristol. Close, though. 321 connects to 421 in Boone and runs together with it for a bit toward Tennessee.
