Wasn’t the lower tier of Winston Cup racing called “Grand National”. V6 engines, and where Buick took the name for their G body.

So, when did the longitudinal templates first get used in Nascar?

The long templates came along with Smokey Yunick's "7/8 scale" 67 Chevelle.

"Grand National" was the original term for the top tier, then it became "Winston Cup Grand National" in 1971, which became "Winston Cup," then Nextel Cup, Sprint Cup, etc. Then there was Late Model Sportsman, which became the Busch series, now Xfinity.

I agree, it seems to me the early "modified" lower division for The Permatex 250/300 previous day races of the Daytona 500 morphed into Late model Sportsmen. I never understood how exactly a modified class with typical aero downsized Studebakers with alternate brand motors and dual quads, etc always ran slower that the full size "stock" Grand National cars, other than budget.
