have a 7 page document titled "Competition Class Rules published by the National Hot Rod Association in 1954. It's mimeographed and in poor condition so won't scan. There are gasoline classes and fuel classes. GASOLINE CLASSES There are three classes for stock cars - A, B, and C. No super stock. That came later as did classes after C. There are four GAS COUPE/SEDAN classes - A, B, C, and D. These classes were the cars we referred to as gassers. These cars had to have legal equipment required for operation on the street and had to be registered for current year's operation. There were no separate classes for blown cars. Cars with superchargers were advanced into the next higher class. So if you had a B/G car and put a blower on it you would be in A/G. There were two classes for ALTERED COUPE/SEDAN - A and B. Hoods and grilles required. Chop and channel could not exceed six inches total height reduction. As with gassers, blown cars would be advanced to the next higher class. There were three classes of STREET ROADSTERS - A, B, and C. Body could not be altered in height, width, length, or contour. As with gassers, full street equipment was required although windshields could be removed for competition. May include touring and roaster pickups. And blown cars advance one class higher. There were two classes of ROADSTERS - A, and B. May include touring and roadster pickup. 25% engine setback allowed. And blown cars advanced one class. (Oddly, there is no mention of fenders; I didn't think they were required but perhaps they were.) There was only one class for OPEN GAS - OG. This was for cars that didn't fit any other class. This class was for cars such as those described in the FUEL CLASSES as dragsters, modified roadsters, and competition coupes but which ran on gasoline. FUEL CLASSES There were three classes for FUEL COUPE/SEDAN - A, B, and C. Requirements were the same as for ALTERED COUPE/SEDAN above. There were three classes for COMPETITION COUPE/SEDAN - A, B, and C. Top may be chopped but five inches of verical windshield height must be maintained. May be channeled not to exceed six inches. Sectioning not allowed. Streamlining may be added ahead of the rear of the front cowl and to the underside of the chassis. No fenders allowed. Engine may be in any location. Transmission not required. Quick-change and/or locked rear ends are permissible. Blowers advanced to next higher class. There were two classes of HOT ROADSTERS - A and B. All other requirements same as ROADSTERS above. There were two classes of MODIFIED ROADSTERS - A and B. Requirements for streamlining, fenders, and blowers same as COMPETITION COUPE above. There was one class for DRAGSTER - D. Must have some type of body made of fireproof material that encloses the front, sides, and back of cockpit. NOTE: At strips where participation is limited in the dragster, modified roadster, and competition coupe categories, an OPEN FUEL section may be substituted to combine these three into one group. There were several general regulations defining service station pump gasoline and describing car weighing procedure and protest procedures. Consider: There were three classes for stock cars and nine classes of various kinds of roadsters. Hot rods ruled!
Hey FC, Yes, scans are hard to pick up old mimeo images on paper. It depends on how bad the mimeo copy is in its original state. Take a digital photo and use your photo program to turn it into a b/w copy. Then try enhancing it and adjust the photo for clarity. It might be worth the effort. Also, you could try raising your scans to 600 dpi or even 1200. Jnaki
