Trying out a spreadbore carb on the Duster.
What your misunderstanding is that square bore carbs are not always exactly square between the front and rear. Typically, they are like the Holley is. 1.75 on all 4 barrels for example.
The square bore is monkier is still applied when it’s like what you have shown.
The spreadbore is a large difference. TQ, Quadrajet, select Holley carbs are spreadbore.
