STOCK CLASS: The entire car must be completely stock, engine (Model A only), transmission, rear end and tires. Safety upgrades are permissible, such as steering and brakes. Seat belts and helmets are required in open cars (roadsters etc.) And recommended in all cars. Class designation will be S-1, S-2 with ST class for touring type cars. Some minor changes are allowed in ST class.

MODIFIED: This class is for basically stock cars (steel bodies) that have been modified for performance and safety, and may include minor custom treatment. A full production body mounted on an original frame is required; body may be chopped and/or channeled, fenders may be removed, aftermarket lights, different year radiator shell and/or other modifications as long as the car remains easily identifiable as a Model T, A or B Ford. The cars in this class must retain seats for the number of passengers the car was originally designed for and all structural components (door metal, wood etc.) must be intact. These must be roadworthy cars, no gutted interiors, radically chopped tops or engine set-back. Cars in this class must be designed, equipped, and be able to be driven on the street for an extended period of time, i.e., full radiator, lights, charging system, etc.
Body, frame and engine must all be alike (T body on A frame or an A engine in a T, etc. will be classed as a speedster). A & B blocks or G-28 blocks will be considered the same in these classes.
Engines must utilize the Model T, A, or B Ford block but any aftermarket cylinder head designed for the Ford block, and any manifold may be used as well as any number and type of carburetor(s). This class may utilize any automotive production standard-shift transmission and/or rear end, regardless of year. Trans must be complete with all forward speeds and reverse. Automatic transmissions and Quick-change rear ends are allowed in M-5 and M-6 only. Overdrives may be utilized (shifted) There will be six classes, M-1 through M-6.

SPEEDSTER: Any aftermarket speedster body, special built body or modified production body mounted on a factory production frame, or replacement copy (no multi-tube frames), may be used with wheelbases no shorter than 84". The frame may be boxed, reinforced, zee'd or aligned slightly at the rear to follow body contour, but can not be narrowed. (Also see Modified section regarding T bodies)
All major components, radiator, engine, trans and seating for two (or more),must remain in a relative stock location, and a full size gas tank of 8 gallons capacity or more must be used.
Cars in this class must be designed, equipped, and be able to be driven on the street for an extended period of time, i.e., full radiator, lights, charging system, etc.
Mechanically, speedsters must comply with the rules for Modified class cars as spelled out above. Quick change rear ends and/or automatic transmissions are allowed in this class.
It is strongly recommended for all cars in this class to have roll bars large enough and strong enough to protect the driver in case of roll-over. See General Requirements and Safety section.
There will be two classes, one for flathead cars and one for OHV equipped cars. SP-1 & SP-2.

HISTORIC CARS:* Other vintage 4 cyl. cars, i.e. vintage race cars, that do not fall into any of the above categories may be allowed to run provided they meet all the safety requirements and there is space available for any special consideration (i.e. tow starts and/or enough shut-off area). This can vary from hill site to hill site. Check with the people running each event to see if you will be allowed to run your car. Historic cars are exempt from the 4-wheel brake rule. Pre-1935 only, 4 cylinder engines only. Class designation: H.

* Model T's (with T engine, trans & rear end) are exempt from the metal wheel, shocks and brake rules unless they are quicker than 10 seconds and / or faster than 50 MPH, they must then have "Rocky Mountain", or equal, brakes and metal wheels.

TIME ONLY: For all vintage 4 cyl. cars powered by non Ford-built blocks (Chevy, Essex, etc.), and those that do not fall into any of the above classes, but meet the safety requirements. Hill climb organizers to make any decisions that may be necessary. Pre-1935 only, 4 cylinder engines only. Class designation T/O

ANY CAR EXHIBITING ILL-HANDLING TRAITS, IN THE OPINION OF THE SAFETY COMMITTEE, WILL BE BARRED FROM FURTHER PARTICIPATION.

Rules cannot be written to cover every situation that may arise, therefore with safety as the prime ruling factor:
THE DECISION OF THE SAFETY COMMITTEE IS FINAL

Revised 11-11-07

You may have read here that we will test run a new format this year whereby the cars would not be placed in classes. Well, we have now decided NOT to change the format so cars will be placed in classes as in the past.

EVERYONE running the hill will receive an award at the end of the day and timing tags will be supplied after the event.
