In a word....YES! i just swapped out my stock 4BBL single plane intake for a edelbrock LD4B intake & it picked up low end grunt it never had! Plus i use a wide band 02 meter to tune the carb. After installing the LD4B my air fuel raito cleaned up 12.6 beforehand to 14.4 at cruising light throttle! that's doing nothing to the carb just bolting it on the eddy intake & go! Pulls a lot harder @ lower rpm. It will surprise people when i tell em its a .030 over 273! Dual plane it the way to go man!
