sb vs BB

Well my wife is going to be the driver of the car. HER dream is to have a straight axle and a blower in it to compete with the A/FX cars at our local track. I have told her that the 74 isn't the right year car for that era of car/set up. She says that she just wants to be able to race them and have a chance of competing. They are in the mid 8's. I would be happy with the car in there too. Realistically probably no blower and in the low to mid 9's
