Dodge has offered its Challenger Drag Pak, a heavily modified production car built for several stock-esque divisions of drag racing, for years now. Likewise, Ford Racing has put together a Mustang Cobra Jet package for the same purpose.
Chevy's entry is said to be ZL1-based, according to LSXTV, and may get the title of Stock Eliminator, after one of the classes it'll likely be eligible to compete in. So far there aren't any details on the package, either performance or otherwise, so keep your eyes peeled for more to come soon. One thing we do know, however: having all three of the American muscle manufacturers in the game will only benefit the competitors.
