Yep, he has. He ran all 3 mile dirt races in 2011.

Yung Muny actually won the Ted Horn Memorial 100 driving the IWX sponsored Keith Kunz owned #71 Silver Crown car. It was the second most thorough ass kicking I've ever seen a driver administer on a 1 mile dirt track in a Crown car. The late, great Bryan Clauson and Larson put on an epic show slugging it out for the lead in the first 30 miles of that race. BC faded later on in that race and Larson won it by more than a straight away.
