So did it have the air grabber with the 440 4 bbl from the factory, that had the single 4 bbl base that sealed to the air grabber hood? Then you installed a six pack on there. Did the air cleaner base for the six pack line up with the air grabber on the hood to mate-up with the seal properly? Without any further modifications, just swapping 4 bbl to 6 pack and the proper air cleaner base to seal back up properly to the air grabber in the hood???
