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.

The Honda Engine falls right into D2 rules. D2 Midgets I guess you could call the equal opportunity division of the Midget race group. Kind of like a throw back to the 40's-60's when a midget had to meet certain dimensions body and frame size and engine displacement. They ran out board motors (Boy they smelled good), Motorcycle engines, small automotive engines and the trusty old 110 Offy. In the 70's special motor designs began to emerge and the run what you brung gang was displaced, and dis-appeared from the scene.
Just recently automobile engines and small motorcycle have emerged with 4 valve heads that are vastly superior to the old push rod 2 valve design. Motor cycle engines as small as 60 cubic engines are pushing 200 Horse Power right off of the bike. That fact lead to the development of the Mini Sprint race car (Midget Chassis powered by a Crotch Rocket Motor). A few years later the auto makers started making a modern 4 valve engine for the newer car design, (Thank You EPA). These motors while around 120 cubic inches to 150 cubic inches also produce around 200 Horse Power in a nearly stock state, Thus the invent of the Focus-Ecotec-Honda Midgets. All the racers had to do was figure out that all of these Midget Frame based Midget racers were very competitive with one another and I'll be darned the Idea of D2 Midgets was actualized. Just like falling off a log.
