Thermoquad on a 440 low comp engine

The 1974 Ford 460 Thermoquad is the 800 cfm. Don't know why they used the small one on the 460, another thing they used their screw in fuel filter with a 1/4 hole. So the Ford guys never got to see how good their 460 could run with the 850 carb. I think most of the International models used the larger TQ's.
