You say the 305 is weak in the lower end? Your wrong they are identical. Only difference is the bore. Same crank, same connecting rods. The only difference is .250 in the bore period. If you get into the 350 the slightest little bit and your mileage goes out the window (got to fill up that bore). I get religiously 27-28 mpg overall in normal mixed driving.
