I found by reading the complete ascs sprint cars schedule The only group that is having any races during the 360 nationals is sod . Does that mean if Dallman & Daggett go to the ascs nationals they will be penalized ( no points) for racing in Iowa
even if they are ascs 360 races

just wondering?
"Penalized" is a bit of a harsh term. Any driver from SOD going to the Nationals - it is their choice. Some guys don't set out to run the whole SOD season. They'll run the Nationals, and other big events down the Ohio way. Others (the majority) stay close to home and run the smaller events, like Cherry Speedway, during the Nationals. So, by running the Nationals, sure.... the driver(s) will not accumulate SOD points.
I am sure it all comes down to time and money.
But, if you are asking WHY they (SOD) schedule races during the Nationals, that's not for me to answer. I can make a good guess, but it is just that - a guess. I'm just a fan like you.
