The ignition system must be stock, including the distributor, cap, coil, and wires. Points may be replaced with any electronic conversion that fits under the stock distributor cap. Replacement coils are allowed as long as they are the correct shape, color, and size. Coils must be mounted in the correct location with correct brackets for the make, year, and engine combination. We will no longer allow the use of aftermarket ignition boxes like MSD, Crane, Jacobs, etc. We made this decision based on participants using these ignition boxes for traction and total timing manipulation while making runs. You will be allowed to use a rev limiter, but the unit must be only a rev limiter and nothing else. Spark plug wires must be of correct appearance in size and color for the vehicle.
The battery must be retained in the original location and securely fastened down with the original style hold down. The charging system must be fully operational at all times. The removal of the alternator belt is not allowed. Lightweight batteries are NOT allowed.
Pulleys: All pulleys must be factory issue and be correct diameters for the year and horsepower claimed for the engine. Belts running the water pump, alternator, and power steering must be retained at all times. Air conditioning belts may be removed if they do not affect other components.
