When I lived in Michigan it was Best Machine. Now that I’m in Tennessee and stepped down to a slower car to run 1/8 mile on our local outlaw track I use a local guy here in town. Stan is 84 years old and got started building engines for the local moonshine runners many years ago. Why he is just down the road from me and all the locals highly recommended him. I have 271 passes on the engine and it is still going strong.
