  • All entries must be driven onto the judging area.  They must be completely operable and should be able to start, pull forward, backward, turn and stop under their own power.

All entries must remain on the show ground until the end of judging.  Early departures may be approved by the Head Judge.  Unapproved early departures will result in the forfeiture of an award.

Entries to be judged must have their completed judging form in an available, conspicuous location at their vehicle during judging hours or they may be disqualified.

Each entrant or their representative must be present for his or her vehicle’s judging.  If this presents a problem due to a conflict, the entrant must coordinate with the Class Judge or suffer possible point deductions.  The Class Judge has the final authority as to when he or she wishes to judge the entry.

All entries must have an Oldsmobile body and a GM engine.  If the engine is not an Oldsmobile engine, it must be a production installation.

A vehicle brought to the show, which is different than the vehicle registered cannot be judged.  Hardship cases may be considered by the Head Judge.

The method of ascertaining the operational capabilities of an entry is left to the Head Judge.  Possibilities include random checks by each team, uniform checks of specific items by each team and drive-through safety checks.

Convertible tops will be judged according to the judging form and each entry may be displayed as its entrant sees fit.  Whether the top is up or down, the top, it’s boot and rear window must be examined.  All convertibles had boots.

STOCK/RESTORED STOCK: Car is as it appeared when new plus any accessories of that era.  Items that are “wear-dated” and have been replaced, such as tires, shocks, mufflers, filters and battery do not exclude a vehicle from the “Stock Vehicle” class.  Dual exhausts do not force an entry out of this class.  Any other item that has been replaced for wear is permissible as long as the owner has attempted to restore the item with material or fabrication as close to the original as possible.

STREET STOCK: A Street Stock car may not have any of the modifications listed under MODIFIED (below).  A Street Stock must have dual exhaust.  A Street Stock must have either (1) changes to the sheet metal and trim, or (2) improved carburation or ignition.  Changes which do not affect the vehicle’s “street performance,” e.g. electric fuel pump, 12- volt battery, mag wheels, engine chrome, radial tires, etc. do not alone qualify the vehicle for Street Stock. Dual exhaust alone does not qualify the vehicle for Street Stock.

 MODIFIED: A Modified vehicle has one or more of the following:  (1) A non-original power plant which is either “high performance” or an increase of more than 50 cubic inches. (2) Major body modifications. (3) Chromed or de-chromed 30% or more. (4) Major change in riding height. (5) “Custom” paint. (6) Hood scoops (not original). (7) Car set up for racing. (8) Non-stock suspension, other than shocks. (9) Differential other than year of manufacture.

UNRESTORED CLASS: An unrestored vehicle is one that has no more than two of the following repairs.  Each numbered item or position thereof is considered one repair.  Items 1 and 4 may not exceed the quantities listed.  IF they do, the entry must move to the Stock/Restored Stock class.  (1) Two panels repainted  (2) New trunk interior (3) One-half of seat cushions/backs replaced (4) Two glass panes replaced (5) Headliner replaced (6) New floor covering (7) Vinyl/convertible top replaced (8) Bumpers replaced or rechromed (9) engine repainted.  All qualified cars in this class will receive recognition but will not be judged for First, Second, Third or Best of Class awards.

SENIOR:  When an entry wins Best of Class at any NAOC National Meet, it is then placed in a senior class.  Once an entry wins Best of Class in its senior class, it is then retired from competitive judging and advanced to Preservation Senior.

PRESERVATION SENIOR: This entry is still judged but competes only against the judging form.  At each National Meet that a Preservation Senior entry attains 900 points or more, it shall be recognized with an award.

RECLASSIFICATION AS A JUNIOR: If an owner wishes to reclassify his entry after it has won a BOC and moved to Seniors, not only are modifications required that would reclassify his entry, but the Head Judge must be satisfied that the owner has made sufficient changes to warrant the reclassification.

SENIOR/PRESERVATION SENIOR DROP:  If the owner of one of these entries wishes to be removed from either of these classes, he must adhere to the following procedure:
Select the two lowest score sheets from any of the preceding five National Meets.
Ascertain that they do not total more than 1800 points.  Non-attendance or a lost scoring form will be counted as 901 points.
Notify the Head Meet Judge with copies of the past judging forms prior to the closing of registration.

Change of ownership does not affect the classification of an entry.

Awards will be made as follows: All entries scoring 700-799 points: Third Place; all entries scoring 800-899 points: Second Place; all entries scoring 900-1000 points: First Class.

The highest scoring entry in each class will receive the Best of Class award providing that entry has scored at least 900 points.

In case of a tie, the Class Judges or the Head Judge will review the operational integrity of the tied entries.  If the entries still tie, then one point will be added to the score of the vehicle that was driven the furthest to the meet.

Upon reviewing the final judging results, if the Head Meet Judge finds an entire class is judged too low, he or she should review that class.  If, in his or her opinion, the judges were too severe in their judging, the Head Meet Judge may assign any number of points necessary to more accurately reflect the proper points to be awarded.  This point assignment must be uniform through the class and each judging form should be so noted.

Large “For Sale” signs are prohibited.  If they are larger than 5”x7” or they face forward, judges are instructed to deduct 10 points.

A judge may not judge a class in which he has participated in the restoration of any of the entries.

A fire extinguisher must be displayed with each entry.  Entries with missing extinguishers will have their scores reduced by 20 points per missing extinguisher.

Paint does not have to match the color code on the vehicle.  If the vehicle was offered only in certain colors, then the entry must be one of those colors.

Accessories of the “era” will be treated as dealer options.

There is no penalty for updated safety equipment.  This is restricted to seat belts, tail/brake lights, fire extinguishers, directional signals, battery disconnect switches or any item required by law.  Accessory gauges may be added only if they were available as factory accessories.

An NAOC show is a Concours and not a drag meet.  Tire squealing, hot rodding or loud radios are cause for penalties ranging from point reduction to disqualification from the meet.  Enforcement of this rule is the responsibility of the Head Meet Judge and the NAOC president.

A long distance award will be presented to the vehicle that was driven the longest distance to the meet.

Any entrant may challenge the operation or classification of a fellow entrant.  The protest must be filed in writing with the Head Meet Judge and must be accompanied by $20.00.  If the protested item proves to be satisfactory to the Head Meet Judge, the protestor shall forfeit the $20.00 and the $20.00 shall be given to the general proceeds of the meet.

All complaints and controversies should be directed to the Head Meet Judge and his or her decision will be final.

Each national meet may publish their own supplement to these rules.  In case of conflict these NAOC Car Show Rules will govern.

Judging forms will be made available to entrants upon request after the meet.
