Interesting, I didn't think anything about that name, just thought it was a name. I found this old article about it. I knew that Abru's car was running a Volkswagen on Stewart's team. I might have been looking at some in the early Chili Bowls, I believe Voegler's car was VW powered, but they ran all kinds of stuff back then. 4 cyl Fords, Chevy's and VW's. Looking closely at the second pic in this post it sure looks like Stewart has the short wheelbase Munchkin version.^ The Munchkin ... serious indoor car.
It was just amazing to watch them. I went back to the pits on the way out and shook Michael's hand and told him how great it was to watch.That was one bad ass race, those guys were rubbing like they had fenders. Nothing but slide jobs, blocking, and out right battering
