Ok I have question for the people in the midget world. I understand the "national engine" I think I understand the "D2 engine" class. This were I am a little lost, USAC has a sealed Honda engine. This is the replacement for the old Ford focus program. So if I buy a sealed Honda engine. Can I race another place/class other then in a USAC "Honda" class race? Would the Honda engine be allowed to race with the USAC national engine class. Would the Honda engine be equal to a "D2" class engine (size-horse power-torque-weight)? Is the Honda legal to run under the new "D2" rules? Last year they let old focus cars and 1000 cc mini sprints race with the new Honda engine. If I had a "D2" engine, could I race with the USAC Honda class this year? It seems like we have 3 types of midgets now. Not sure how they match up and over lap to allow for different class use.
