you are going to get a lot of opinions here but in my opinion, the 650 AVS thunder series will run perfect. i would stay away from the eddy 1407 750. i have had nothing but problems with them. the factory 70-71 440 magnum auto's came with a 4966 630 CFM AVS . if you must run a 750 , i would start over with a brand new holley and make sure it is set up correctly. this is what i will be running on my basically stock 440
