What happens when the engine quits?

Now you have an overweight airframe with a humongous engine on the nose. Chances of making the field in a deadstick are slim

Granted the glide path will not change with weight, but the airplane will have to fly a lot faster to maintain a specific angle of attack. Otherwise, at a constant speed, the angle of attack will be higher and closer to stall. I suppose the answer to the question really depends on flying style, but I have found that every ounce of additional weight on my airplanes detracts from the flying qualities.
