The block we started with weighed 225 pounds. Each finished wheel house weighs about 2-3 pounds. (I'd have to check and see if I ever wrote it down). Here you can see Sandwich sawing the billet log in 1/2. The chunk of aluminum is pretty big--but it was the only way to turn the corner on the chassis to feed the rear suspension loads to the front of the car and finish off the tub.
