Thermoquad or Holley?

The rear end is a 1973 8 1/4 I don't know the ratio, its a sure grip but seems like awfully high gears, the whole drivetrain is from a 73 duster 340.

before messing with carbs and all i think you need to do a little more research and find out exactly what you have all the way around..
