NMCA UPDATES PURE STOCK CLASSES FOR MICRO STRATEGIES STOCK ELIMINATOR
BY NMCA STAFF
For many racers there’s a fascination with taking a “stock” vehicle and maximizing its performance. Tuning, tweaking and testing is part of the thrill. With that, NMCA is offering modern Muscle Car enthusiasts an opportunity to enter Championship Class racing, with their showroom stock cars in the revised Pure Stock Classes.
ANY car that is currently listed in the NHRA stock class car classification guide is eligible to run in the Pure Stock Classes of Stock Eliminator, which boils down to most modern American cars. This includes up to date late-model showroom production cars like the Mustang, Camaro and Dodge products.
The NHRA listed Shipping Weights, Horsepower, and Weight Breaks for Stock Class Cars will be used to determine Class fit, Minimum weight, and Index. Pure Stock Indexes will be adjusted race by race as NMCA gains information about performance level of the new showroom cars. EXCLUDED are all factory built Racecars ie: COPO Camaros, Ford Cobra Jets, and Dodge Drag Paks. Pure Stock is more for showroom, production vehicles that start our as street-legal examples.
Keep in mind that these classes are created for basically showroom production cars. The rules will remain basically the same as in past Pure Stock classes, which you may be familiar with as they existed in the IHRA Stock Category.
Here are some of the basic rules:
- Body must appear stock for the year make and model claimed.
- Engine must be correct for the year make and model.
- Must have the stock cam(s). Lift and duration.
- Heads and Valvetrain must be as delivered from the factory.
- Stock Valve Spring Pressures.
- Stock Fan and Water pump must be used.
- Stock pulleys and belts.
- Power steering and AC may be removed.
- Factory pollution accessories may be removed.
- Fuel pump and system must be factory original.
- Stock Suspension only. Stock looking aftermarket Struts and Shocks permitted.
- Any Gear ratio allowed.
- Trans must be correct for the car as delivered from the factory.
- Driveshaft loop mandatory.
- Aftermarket convertor allowed.
- NO trans brakes allowed.
- Any size rear DOT tire allowed. Slicks allowed. Race Slicks limited to 9-inch width. The tread width of any rear tires must fit inside the unmodified stock wheel wells and opening.
- Aftermarket wheels permitted.
- Tube type headers permitted. Stock exhaust system with mufflers must be retained.
- Safety rules, including licensing, will coincide with NHRA Stock Eliminator and/or New Street Cars rules.
