There's more science to it, larger valves (1.84 are the typical 305 intakes, 1.94 will work with certain cylinder heads, 2.02s are right out), cam timing, carb, exhaust, etc. Also factor in axle ratios and weight of car.
As long as the engine can breathe, you should get a decent boost - it will have more torque. Just how much more depends on the above factors and more.
