Geezer Gassers Guidelines & Directives
These guidelines are presented as the basis and foundation for the group and our motto “Drag Racing The Old Way”. It is our belief and focus that all the vehicles competing directly resemble as closely as reasonably possible the gas class vehicles of the mid 60’s – the so called “Gasser Wars” relived. Anything that makes a vehicle look or act like a current generation “bracket car” is cause for immediate disqualification from participation. All decisions made by the technical staff relating to appearance and safety are final. Our focus is safety, entertainment, putting on a good show and having fun. Competitive spirit is welcome, bad attitudes are not. These rules are subject to change and interpretation by the Geezer Gassers technical team. All decisions are final.
All vehicles will be required to meet the safety criteria of the sanctioning body or host track affiliation i.e. NHRA, IHRA, Goodguys VDRA.
Chassis certifications are encouraged for all vehicles, but not required.
Track or sanctioning body technical inspectors have the final word.
Two functioning headlights are required. Permanently mounted in the factory style and location. May operate on only low beams, or high beams, or both. They must be controlled from the interior of the car RESCINDED 2/4/19
At least one working red rear taillight
Wheelie Bar(s) REQUIRED on any vehicle that is capable of pulling the front wheels 12 inches or more on launch or when shifting gears.
All vehicles are required to have in place a non SFI lower engine containment device or a SFI lower engine containment device.
ALL CARS WITH A MULTI POINT MOUNTING ROLL CAGE ARE REQUIRED TO HAVE SFI 45.1 RATED HIGH DENSITY PADDING IN PLACE ON ALL ROLL CAGE STRUCTURE THAT IS IN PROXIMITY TO THE DRIVER’S HEAD/HELMET AREA……..basically from the shoulders up. This applies to ALL cars with a cage. Even those with a simple single hoop roll bar can benefit from installation of this material.
Absolutely NO electronic engine, transmission, or power train controls are permitted in competition.
This includes but not limited to:
Data recorders/monitors/playback systems
Infrared starting line systems
Exceptions to the rule are:
Rev limiter/Playback tachometers/Ignition boxes
Rev limiters can be used only as engine protection. They are not to be used for launch or start line process.
BODY TYPES & Suspension
All body type must be based on a 1952 or earlier year of production. EFFECTIVE 1-1-2014, THE YEAR OF PRODUCTION CUTOFF HAS BEEN ADVANCED TO INCLUDE 1957.
Fiberglass reproduction of complete bodies as well as components are permitted
All bodies must retain the appearance of the original.
NO OPEN OR ROADSTER TYPE VEHICLES. Enclosed cabin, door cars with a permanently attached roof ONLY
No body enhancements or aerodynamic improvements are permitted
This will include but not limited to:
Raised quarter panes or rear fenders
Wings or airfoil spoilers
Pro stock or snorkel type hood scoops
Period type/correct paint schemes are required
No present day graphics or schemes are permitted.
Primer is OK – any color or tinting
Any lettering – driver identification, sponsorship, nicknames must be in good taste – permanent paint or vinyl lettering is acceptable.
Front suspension – straight axle front ends, suspension of the ’60’s a must.
Rear suspension – parallel leaf springs, transverse leaf springs, coil overs and ladder bars are acceptable. 4-link suspension will be considered on individual competition basis.
A LINE ALONG THE BOTTOM EDGE OF THE MAIN BODY…ie….THE DOOR OR THE LOWEST EDGE OF THE ROCKER PANEL (IF SO EQUIPPED) WILL HAVE TO F ALL EITHER IN LINE WITH THE SPINDLE CENTER OR ABOVE IT. This will in our case, provide uniformity in appearance, and more important, help in the stability of the cars and the safety of their operation.
THE MINIMUM WEIGHT FOR ANY PARTICIPATING CAR IS #2500 lbs. RACE READY, WITHOUT THE DRIVER. This applies to all new prospective members, as well as those under construction.
No full tube/round tube chassis vehicles allowed
Wheels from the period are the only ones accepted i.e. aluminum slots, Cragars, Halibrands, painted steel wheels are the first choice. Absolutely no late generation billet or spun aluminum wheels i.e. Centerlines, Welds

After 1 March 2011, no new memberships will be accepted using this style wheel. Current members using them are permitted to retain them.
These are not permitted/accepted for change to, by current members

Rear tires cannot be wider than 12″ (tread width) and no larger than 32″ tall (diameter)
This is a “GAS” class, therefore ABSOLUTELY NITROMETHANE, or other exotic type fuels or additives are permitted. Alcohol blended fuels above pump gas levels of 10% are not accepted….ie, E85 is NOT an accepted type of fuel. Race ‘gasoline,’ leaded or unleaded, of any octane rating is the only accepted fuel for group activities. NO NITROUS OXIDE IS ALLOWED. EFFECTIVE 1-1-2014, METHANOL AND ITS DERIVATIVES (E-85) ARE NOW ACCEPTED FUELS
Engines are permitted, any OEM or after market iron or aluminum cylinder head.
Superchargers are restricted to Roots type only, no larger than 8:71. No screw, Whipple or centrifugal type.
No exhaust driven turbochargers.
Any OEM or after market iron or aluminum intake is permitted. Carburetor or mechanical fuel injection may be used for fuel delivery alone or with supercharger.
Any transmission may be used to include full automatic, stick shift or manual, clutch flite or hydromatic.
Any ignition type i.e. magneto, points, transistorized or MSD.
Car will have to be self starting (no remote battery carts or starters) and will have to drive under it’s own power from the pits to the staging lanes. After the pass down the track, the car must drive under it’s own power down the return road to return to the pit area.
In the same note of safety and stability (as much as possible), THE ENGINE CRANKSHAFT CENTERLINE (AT ITS HIGHEST POINT) CAN BE NO MORE THAN 24″ ABOVE GROUND LEVEL.
