In the world of outlaw street car drag racing, the X275 class is popular for racers and it’s popular for spectators. It offers up a lot of cool combinations, from conventional nitrous-fed big blocks to all sorts of boosted applications. Fox body Mustangs are a common platform for the class, but no two are the same, thanks to an extensive rules package with minimum weights that fall into the fox body’s favor. Despite the number of Mustangs on the property at Memphis International Raceway, the X275 field is packed with awesome combinations, ranging from a clean and simple ’67 Chevy C10 pickup to an over-the-top turbocharged Dodge Challenger. And while many of the cars feature sponsor decals and plenty of race-ready equipment, we dig the ones that look like they just rolled in off the street.
The rules for X275 are lengthy, but to sum it up, the cars (or trucks) must retain the original appearance, meaning stretched wheelbase and wild aerodynamic body panels are not allowed. Mini tubs are allowed, but the vehicle must use its stock frame (or unibody structure) and rear suspension configuration. Engine size is limited, depending on the combination, and it is a single power adder class with many restrictions on turbo size, supercharger type and nitrous system specifications. Minimum base weights are determined by the car’s power plant, and range from 2,300 pounds (N/A small block) to 3,350 pounds for the most aggressive boosted big blocks in the class. Tire size is limited to 275/60R15 drag radials.
One of the top contenders in X275 is Ron Rhodes, who campaigns a beautiful ’68 Camaro, which has a seemingly simple setup—a small block Chevy on nitrous, a single carburetor and leaf spring rear suspension. Ron and his crew make it look easy, and he cranked out a 4.544 at 154.41 miles per hour on his first test pass of the weekend. Friday’s qualifying action on the track was delayed, due to weather, but many of the racers were able to make a test pass to prepare for qualifying and eliminations on Saturday and Sunday. Judging by the cool temperatures and outstanding track prep crew, this weekend of racing at the Outlaw Street Car Reunion will re-write the record books in all of the heads up classes. Take a look at some of the X275 contenders and watch for updates and photo galleries throughout the weekend.
