I was under the inpression it was called the Type 547 engine Also called the Fuhrmann 4 Cam, named after Ernst Fuhrmann and future chairman of Porsche. Hirst was the manufacture of the roller bearing crankshaft that was used in the 547, A version of the Hirth crankshaft was also used in some racing 356 engines.
I actually never heard anyone refer to it as a Hirth engine
