wellll, I have used 750DP carbs on everything including a mild 340. Now the Eddy 750 is a tad different. There's no reason it can't work. You are just going to have to tune it and the car. What is the build? Even a low compression 440 can run 12's (AMHIK) it's all in the tune. We need to know more info to help. Cam, stall, gear... and so on. I'd start by turning the idle mixture screws in all the way and out 1.25 turns, then start the car. turn the rpms up to 1400 set your timing in full at 38*, back it down to 800 rpm and set the carb for best vaccuum. A 4 hole 1/2" spacer might help.
