Difference between 360,340 and 318

I am just wondering what kind of HP and TQ differences I would get between each of the small blocks. We will say that the boost will be supplied by a 6-71 type of blower and be limited to 8 lbs. Everything else on the engines would be the same, ie: heads, cam, compression ratio, exhaust, carbs and ignition. compression would be 8 to 1.
