I'm definitely with the majority here..for a reliable driver, they can't be beat..on the BBC in my Chevy truck, I was playing around and swapped the tricked out Holley 850 double pumper to an out of the box 750 Edelbrock and the seat of your pants power decrease was very noticeable, but it started so much easier and idled a lot better..
I'm going to try two Edelbrock 600's on the tunnel ram in my F1 project..
I have heard that Edelbrock and Holley measure their CFM flow in different ways, maybe at differing air pressure, I'm not sure.
Thus the 500cfm Edelbrock, apparently, flows almost the same as the 390 Holley, so I'd guess your 750 flowed way less than the 850 rather than just the 100cfm you'd think.
