650 or 750 cfm. carb??

well i would like performance but from my experience the edelbrock also has great performance. My dad put one on his very healthy 440 in his 69' charger and he loves it way more then the holley he used to have. mind you it's an 800 thunderseries (or 850 whichever they are??) but i don't know how much difference that there can really be. you say holley is the a certain line that i should be looking at?? Thanks for the info. guys
