While Q- jets are generally good , due to small primaries I have had good luck with some smaller eco crabs . damn, its been long time but I think Holley made them in 450 and 600 cfm which is much smaller . not sure they make them anymore ,they were made to replace Q-jet .
Whatever you do don't use holley performance carbs, there terrible for mpg and need tunning all the time .

Edit: forget my post as i don't see the carb made anymore ,could not find it .
