Classic Car Insurance Hagerty vs Grundy

How do the other companies handle racing?
I was up front and told the Hagerty rep on the phone that I intended to drag race and possible Autocross the car. I was told that Hagerty will insure the car but the coverage is not in effect while the car is being prepped for racing or participating in on track events. I will get a better definition on how Hagerty defines 'prep for a race'
Grundy and American National both declined to write any coverage on a vehicle involved in racing.
