It is pretty easy to do a drive by inspection of a motor and tell if it will be a power house or a louse. Engine builders call it the "Port window" When you look down the intake port from the outside>>>just how much of the intake valve can you see. The more valve the more power>>>that is why the displacement argument is fruitless because the real power is in the port design>>that is why a 1000cc motorcycle motor can hang with a motor more than twice its size. When I look down the port of my Kawasaki I see about 7/8th of the intake valves. How much of the intake valve do you see when looking down the port of a Focus Motor? Then an Ecotec? As old Shakespeare would say, "Thereby hangs the tail". Don't get tied up with rules that don't add up to a hill of beans. A motor 50 cubic inches smaller than another can outperform the larger one simply because of Volumetric Efficiency. Decide on a displacement representing the size of the majority of cars found in the salvage yard close to what you are racing and let the racers experiment. I would think 2500cc or 3000cc and do away with the odd ball 2436cc or whatever it is.

I'm ready for a name change "Junk Yard Midgets" that is a much easier name for us low budget racers to get our head around. and we might decide yeh I might be able to afford one of them cars myself.
