I prefer Holleys too. I had a 750 double pumper on my old truck..so easy to tune. Edlebrocks have those damn metering rods and other crap....confuses me. But they are better suited for street only daily driving. For a stock 305, I believe a 750 of any kind would be a lil too big. Like I said, try to find a 650, it should work better. It's a small, stock motor, you shouldn't need something as big as a 750.
