FACTORY SPEC SHOOTOUT

A Big Announcement, Coming in 2025 in the Modern Street Hemi Shootout series. MSHS along with Blackbird Performance are excited to announce a new class, Factory Spec Shootout.

A first for the Modern Street Hemi Shootout series, a new class where factory race cars (or clones) from Dodge, Chevrolet and Ford will all battle in head to head competition. Launching heads and wheels up, running side by side, deep into the 7s in competition, Hemi powered Dodge Drag Pak Challengers will run against the LS powered Chevrolet COPO Camaros and Coyote powered Ford Mustang Cobra Jets until the last one rolling. The intent, give these cars a place to do what they were built to do with a format and rules, that allow them to do it repeatedly, at a much lower cost and with rules that are understandable, enforceable and allow the freedom to run deep into the 7s while getting it done.

The class will be open to all years of Dodge Drag Pak Challengers, Ford Cobra Jet Mustangs and Chevrolet COPO Camaros (or clones) of these factory built race cars. The engine rules will allow the use of the factory equipped engines and superchargers but with a host of allowable modifications along with the option to use any more readily available factory (or accepted) cast block and/or cast heads for the engine platform in the car (G3 Hemi, LS, Coyote). Engines can be built to any engine displacement preferred and there are no RPM limits. Any camshaft and head porting of your choice. Any supercharger drive ratio and any supercharger modifications are allowed along with the option to utilize a Whipple 3.8l supercharger on any of the three engine platforms. You’ll still have to shift and drive with no electronic assists of any kind. Minimum weight for all three will be 3,550 lbs and they will continue to utilize a 9″ wide x 30″ tall slick. All cars will leave heads up on a 7.70 index, get there first and go 7.70 or slower, you win; run between 7.69-7.60, double breakout rules will apply; and any run below 7.60 will result in disqualification.

The AFFORDABILITY of running these cars in HEAD TO HEAD competition will be dramatically improved BUT the wheels up, launching side by side, full body, factory race cars on small tires EXCITEMENT, will not be reduced, rather enhanced. With estimated costs one tenth of the all out, true heads up style racing, the hope of this new class is to get far more than the couple handfuls of the 200 plus Drag Paks, Cobra Jets and COPOs out of the garage and to the track.

All this and it’s $2,000 to win at each and every MSHS event, with the potential of more from added sponsors coming, and with on going discussions of other adjacent series picking up the same rules.

Stay tuned for more details but most importantly take that car cover off that Drag Pak, Cobra Jet or COPO and start getting it ready.
