Reading through the rules a little slower I noticed several points that were kind of confusing to me.
A------A protective cover may be used on the top of the tail tank providing it is no more than 9 inches in height, 12 inches in length and not wider than the top (head rest) of the tank.>>>>>What are they talking about??
B-----Only chain driven or driveshaft driven cars are allowed.>>>What other drive system is available?
C----- Metal chain guards are required for chain driven cars. Chains must be located within the frame rails. Chain guards must be designed in a manner to completely shield and protect the driver and fuel tank from the chain. The chain guard must be made out of stainless, mild steel, or aluminum (.125 minimum for aluminum).
Chain guards must extend from the firewall to the rear of the sprocket on top and from the top of the chain to the floor pan. The guard must also extend from the firewall to the back of the seat on the side of the driver. Chain guards must be designed so as to not allow chains to damage or puncture the fuel tank in the event they become loose from the sprocket or engine.
This rune is not too realistic in requiring the chain guard to protect the fuel tank. Have you checked the thickness of your chain guard lately??
D------Engine Management Systems may use the following sensors: MAP (manifold absolute pressure), TPS (throttle position sensor), Crank, Cam, Water temp., Oil temp., Oil Pressure, Oxygen sensor, Fuel Pressure, IAC (idle air control, MAT (manifold air temp.), and EGT.>>>>Left out Mass Air Flow Sensor.
Better clarification now than later. The automotive rules just don't ring clear at all to me instead of any motor 2.4 liters or smaller they have actually limited it to 7 specific motors. As a racer I like to experiment and a lot of racers also like to experiment and when you rule out the ability to experiment you also loose a few racers.
Watch out for that little Chrysler Motor guys.

It will probably be a game changer.
