IHRA is lookin' better, all the time... pure stock, maybe?

WHy dont they have Fuel Injection/ Stock? I thought that they had these cars separated from carbureted cars, a while back...
Im gettin ready to start on my 400/330 combo... i should just build my '72 Lemans Stationwagon , instead... 455/250ish hp... I'd be away from most , or all of these cars...
