The rules for 2010 will be posted once they are available.
The most important rule: Your musclecar must be stock, except for the modifications outlined below. If a modification is not mentioned, keep it original! Remember, the goal is to have fun drag racing your musclecar. See old friends, make new ones, and enjoy all the cool cars on the track!
For 1955 to 1974 musclecars built in United States and Canadian assembly plants with a minimum warranty of 12 months and 12,000 miles. Factory lightweight cars built for sanctioned drag racing and dealership-built/modified cars are not eligible to participate. Cars must be factory equipped with a minimum of four-barrel carburetion, dual exhaust, and other factory-installed equipment that promotes a high-performance intent and image. Cars are paired up based on time trial e.t.s and compete in a best-of-three heads-up shootout.
The original appearance must be maintained. No aftermarket panels of any kind are allowed. No "custom" paint colors, designs, or lettering are allowed. The car must maintain the stock ride-height. Raising or lowering either the front or back of the car is NOT allowed. The car must have a presentable appearance. No primered areas, mismatched paint, or large rust-holes allowed.
Bumpers must retain all original bracing and reinforcements. Inner fender panels, front and rear, must be retained. Factory hood scoops, ram air, and fresh air induction must be correct for the year, make, and horsepower claimed. No aftermarket or homemade induction units of any kind are allowed. The factory air cleaner and filter must be in place during all runs. Aftermarket air cleaners NOT allowed. Air cleaner lid can be raised no more than ½-inch off the base.
Interior seating, trim, and materials must be correct for the year and model claimed, as well as being completely functional. Aftermarket tachs and gauges are allowed if mounted on the steering column or under the dash, except for some factory tachs mounted on top of the dashboard. All accessories must be functional (radio, wipers, heater, blower motor, turn signals, etc.). OEM glass only. All windows must be functional and closed during all runs.
The trunk must appear stock at all times.
Automatic Transmissions: The transmission must be correct for the year, make, model, and horsepower claimed. Shift improver kits are allowed. Aftermarket shifters are not allowed. No manual valve bodies. Lightweight purpose-built, drag racing transmissions NOT allowed (for example Pro Trans, Kilgore, etc.). Just switching to aluminum drums is illegal. Anyone caught will be banned from the event until corrected! Torque converters must be within 1 inch of the stock outside diameter. Maximum stall limited to 2200 rpm. Higher stall speeds will require factory documentation. Manual Transmissions: The transmission must be correct for year, make, model and engine of the car. 3-speed manuals may be upgraded to the correct 4-speed if originally available. Aftermarket H-pattern shifters are allowed if no modifications to the floorpan are necessary. Line locks are not allowed. Scattershields are okay. No conversions from column-shift to floor shift allowed unless available as a factory option. Aluminum flywheels are NOT allowed. Rear Axles: The rear axle must be of the same manufacturer as the car. Any gear ratio is allowed. Lightweight driveshafts NOT allowed. Driveshaft safety loops are mandatory on all cars 13.99 and faster! Spools of any kind are NOT allowed.
Engine: Must be factory correct for the year, model, and horsepower claimed. Dealer-installed engines and dealer-performed engine modifications are not allowed. Casting numbers must be correct for the year and horsepower claimed including intake manifold, heads, and exhaust manifolds. Head modifications are prohibited, including, but not limited to, porting, bowl cutting, gasket matching, oversized valves, etc. Heads can be cut to help achieve the allowed compression over advertised. Blocks do not have to be "numbers matching," but they must be the correct displacement. Overbores up to .070" are allowed. Stock cranks only. NO strokers! Random P&G checks are possible. Lightweight cranks and connecting rods are NOT allowed. If found, you will be banned from the event until corrected! Aluminum rods are NOT allowed. Smaller-than-stock rod journals are NOT allowed. Aftermarket pistons are allowed, but piston rings can be no thinner than 1/16", 1/16", and 3/16" for top, second, and oil rings, respectively. Gas porting of pistons NOT allowed. Metric and pressure-back-type rings (dykes, head land, etc.) are NOT allowed. Torque straps allowed. Compression Ratio Limits:
All Engines – 1.5 extra points allowed over advertised. Contact us so we agree on the advertised compression.
Engines with factory dished pistons will be allowed to run either a smaller dish, a flat-top piston, or a small domed piston to achieve the maximum allowed compression.
Engines with factory flat-top pistons will be allowed to run a domed piston to achieve the maximum allowed compression.
Engines with factory domed pistons must run a dome of equal or greater dome volume than stock to achieve the maximum allowed compression ratio.
Heads can be milled and blocks decked within reasonable limits in combination with a), b), or c) above to help achieve the maximum allowed compression ratio.
Electrical System: 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. Fuel System and Carburetor: The carburetor must be correct for the year, make, and horsepower claimed. Jetting and metering changes are permitted. THE CHOKE ASSEMBLY MUST BE IN PLACE AND FUNCTIONAL! Mechanical secondary carbs cannot be substituted if vacuum operated units were original to the car. Mechanical fuel pumps must be retained. Electric fuel pumps are NOT allowed. No fuel pressure gauges are allowed anywhere along the fuel system. Factory fuel lines are required and must be correct size. No rubber lines allowed unless originally equipped as such. No fuel cells are 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. Valve Train: The valve train must be factory stock for the year, make, and horsepower claimed. Rocker arm ratio must be correct for the year and horsepower claimed. No aftermarket rocker arms of any kind allowed. Stock stamped steel or stock cast iron factory rocker arms only. Random requests for valve cover removal WILL happen. Poly-lock type adjustable nuts, jam (crimp) nuts, and adjustable pushrods are allowed. Valve covers must be correct for the year, make, and horsepower claimed. OEM-style replacement lifters only – no trick racing lifters (i.e. ceramic) or shimmed (limited travel) hydraulic lifters allowed. Maximum valve spring SEAT pressure allowed is 130 pounds. Higher seat pressure will require factory documentation. Factory spring configuration must be retained; that is, if your car came with single valve springs, you must run single springs. If it came with dual valve springs, you must run duals. Beehive valve springs are NOT allowed. No aluminum or titanium valve spring retainers allowed. Camshaft: The camshaft must be correct for the year, model, and horsepower claimed for the type of lifter (hydraulic or solid). Roller cams NOT allowed. Duration at .050" lobe lift must be within 1% of factory specs. Lift at the valve must be within 2% of factory specs. Engines must be able to produce at least 16.0 inches of vacuum at 1200 rpm. However, some factory-produced engines were not able to generate 16.0 inches in showroom condition, so those cars will be given a variance to the rule. Solid-lifter cams lift checked at zero lash. Exhaust: Cast-iron exhaust manifolds are mandatory and must be correct for the year, model, and horsepower claimed. Internal modifications to the exhaust manifolds are NOT allowed. Under no circumstances will headers be allowed, including those cars that came with headers delivered in the trunk. The exhaust system may be upgraded to a maximum of 2.5-inch head and tail pipes. Pipes must be routed as they were originally for the year, make, model, and engine combination. Mufflers must be stock looking in design, that is, oval in shape. No glasspacks or straight pipes allowed unless installed as original equipment. Maximum muffler inlet and outlet size is 2.5 inches. X & H pipes allowed. Ignition System: 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. Cooling System: The radiator must be correct for the year, make, model, and horsepower claimed. No lightweight, aluminum radiators allowed. Overflow catch cans of at least 16 ounces are required.

Traction devices are limited to hop-stop bars for the upper control arms on coil-spring cars. Pinion snubbers and clamping of springs are allowed on leaf-spring cars. No slapper bars or ladder bars of any kind allowed unless originally equipped from the factory. Factory documentation will be required to prove authenticity for any car equipped with bolt-on traction devices. No dealer-installed traction devices allowed. Aftermarket upper and lower control arms for coil-spring cars are not allowed. Raising or lowering of the rear end is not allowed. Tires and Wheels: Reproduction tires or radial tires only. No soft compound tires of any kind allowed. Retread tires are not allowed. Use of traction compounds or rubber-softening chemicals on tires is strictly prohibited.

All four tires must be the same size. No 60-series tires will be allowed unless they were originally available for the car's year and model. 60-series tires must be run on 15-inch rims as they were originally. Cars built before the introduction of 70-series Polyglas or Wide Ovals are allowed to upgrade to 70-series of appropriate size. Factory wheels only. Wheels must be correct in size, offset, and style for the car's make, model, and year. All four wheels must be the same size and offset.
Excessively worn or bald tires are strictly prohibited! TIRES CANNOT BE WORN DOWN TO THE TREAD WEAR BAR INDICATORS.
Suspected Violations, Required Tear Downs, and Banning from Race
Deviations to any of the rules are grounds for disqualification, unless backed up with authentic factory documentation. Refusal to be teched in any area is grounds for disqualification.
BANNED FROM THE RACE RULE! Starting in 2011, if we suspect that you are using lightweight internal parts in your engine or elsewhere in the drivetrain, or we have any other issues with your car, you will be asked to tear down prior to the next year’s race for complete inspection. If you refuse to do so, you will be banned from the race until you do.
Drivers must wear long pants. Cars 13.99 and quicker must have an approved Snell 2005 helmet! (This is an NHRA rule, and the track will enforce it. Update your helmet or the track will ban you from racing.) Batteries must be secured down. All cars must have seatbelts for the driver. All wheelstuds must be present and lugnuts tight. Radiators must have an overflow catch can of at least 16 ounces. All accessory belts MUST be in place and tight to operate the water pump, alternator, and power steering (A/C belt may be removed). Cars 13.99 and quicker must have a driveshaft safety loop! We highly recommend carrying a fire extinguisher in your car at all times. No passengers allowed in participating vehicles.
Attention: Please Read
No passengers allowed in participating vehicles.
Wristbands for drivers mandatory.
Guest driver wristbands mandatory.
If you run faster than 3/10 during shoot-outs, you forfeit the shoot-out.
