Dual quad info
back in the day i ran the offy intake on my mild 383 in a 65 coronet 500 with holley 4010's (discontinued) with 1:1 linkage. then on my 440 in a 68 coronet r/t with comp afb's. both using threaded heim linkage with the idle speed adjustment screw removed from the rear carb. I used a drop link with jam nuts (cut down pushrod tapped to fit the stock cable end on the bottom and heated and flattened at the top for an eyelet to put the carb to carb rod through and adjust to cable length) no chokes. As stated, the carbs will only pull what's needed. strip kits were a must but i only had to upsize the mixture rods one size to get a good idle afr. driveability and performance was great on both cars
