“What a way to start Speedweeks here by putting both Ford Mustang RFKs on Victory Lane,” Buscher said. “It’s not a big show, but we have a very good hot rod here.
“I take off my hat in front of everyone in the store. I know it’s been a busy off-season for everyone in the sport, right? But we have had a lot of changes. It’s nice to see how it plays out.
“I definitely didn’t want that to happen. I am really proud of the effort and our performance on the pits. We are in a good place here – it’s exciting. “
Michael McDowell was second, Harrison Burton third, Kyle Bush fourth, and Christopher Bell fifth.
Martin Trueks Jr., Buba Wallace, Ricky Stanhouse Jr., Lagana and Kevin Harwick also scored points in the top 10.
