Is it possible to make a Holley 750 double pumper work on a 602? I currently have one on my engine now using a 1" carb spacer, 70 jets in the front and 72 in the rear. My problem is when I crack the 4bbl open, it has a bad hesitation. Is the carb to big or does it sound like it needs tuned to make it work? Any insight is greatly appreciated! Thanks!
