I have a '68 GMC pick up with a stock 327, topped with its orignal quadrajet. I am building it to be a daily driver so I want as much gas mileage as possible, not just performance.
I have had a lot of conflicting advice about what carboration would be best for this truck. I have had three versions of the quadrajet recommended. I am not sure how they differ from my stock carb or if it would be worth changing. Any insights?
