Tony -i’m not sure why, but I’ve always been curious about the idea of Pro Classes competing at division races!
I began following the sport in the early 90s and wasn’t really aware until recently that the pro classes used to compete in the Divisional races, that, at least for the last 30 plus years have been exclusively the domain of the sportsman classes.
All I really know is that in the mid 70s when the NHRA switched to a points based championship system, National Event points earned were worth double those earned in divisional races.
So I’ve become curious about the topic: when did the divisional races become Sportsman only?
When were the regional based divisions created?
Were they always the same or have they been realigned?
How many Divisional races were run per during a typical year?
Any other stories related to this topic is is greatly welcomed as well!
I can address a couple of your questions and tell a story directly related to the discontinuation of the Pros at divisionals. I think the regions were started in the early-mid 1960s. There have been quite a few realignments over the years. For example, I _think_ there was a time where Div 6 and 7 were combined. But that didn't last long. Closer to home for me, Albuquerque was in Div 4 for many decades (including hosting a Div 4 WCS in 72 and 73). In a story much too long to type, there came a time where NM was cut in half and the northern part (i.e., ABQ) was moved to Div 7, while the southern part (i.e., Roswell, NM) was retained in Div 4.
As far as the number of events, this has varied by year and by division. Back in the day, when I chased points, there was usually 6 or 7 per division but you could only use points from 5. Lots of nuances to the system that again I don't have the patience to type.
As for the story, I had a friend who had run a competitive Pro Comp car in the mid-late 70s. He wanted to run TF and made the switch. He knew he didn't have the budget or manpower to run national events, so he concentrated on running TF at divisional races. He did this in 1980, 1981 and 1982. I believe that it was 1983 that NHRA dropped the Pros from divisionals. And that was, sadly, the end of my friends TF career, knowing his operation was not geared for national events.
Great topic!
