Dumb question but what exactly makes an SS/HA car?

NHRA rules NHRA SS classes are based on factory HP per pounds of weight, then NHRA factors the factory HP to suit the needs of the politically correct(GM racers usually ) racers that cry about thier competitors ability to outrun them Go to NHRA web site and look up the classs factor for that class and then look up the 1968 Dodge cars and motor combinations I'll bet that the motor is a 440 Magnum rated at or near 375 HP The body style and trim packages make the car fit a certian class, for instance a non RT Charger with a 440 Magnum may fit a higher class (SS/HA or SS/GA) than the RT does(SS/HA or SS/JA) IHTHs
