Well, about all I saw was Chevy & Mopar stuff.
Thread title doesn't specify brands. So, I'll add some Pontiac flavor into the mix.
Most of these teams began racing in the '60's. But some kept racing into the early '70's, & longer.
One major team was the Knafel Pontiac team. May have been the most successful Pontiac race team ever. Went by the name Anderson Pontiac, before changing over to Knafel. Many of their cars were named "Tin Indian".
They raced a variety of classes, among which were A/FX, Stock, & SS/S. Had lots of class & event wins, as well as nat records.
The Junior Stock book says the team had at least 200 event wins. One of those was Arlen Vanke winning the '66 Spring Nats, in a Knafel '66 GTO.
