Could this idea work ? Did other guys did this ? 318 infos

look at these 400-425 hp 318 make about the same tq at 3000 rpm with more head cam etc..
even at 2000 rpm bet these engines are on par or better than the stock 2bbl 318, not saying don't build it your way but generally stock low power engine gonna make the least amount of torque all but maybe the lowest rpm's and probably not by much.
