Interesting! I’m not sure if this is being built for a practical purpose, but an impressive amount of effort was put into building that. Note that the actual 300 is essentially square, 4.00” x 3.98” and the model is slightly sub-square at 3/4” x 7/8”. Not many engines are sub square that I know of except military vehicles and some Jeeps.
