Dont know exactly, but I have been told like 70lbs heavier. Since there is more meat in the sleeves then we dont have to fill the blocks or install the braces on the lifter bores. I fill the entire area with epoxy after installing the brace to keep the block from moving around. I will see how much more net weight. Pontiac 455s benefit with weight on the front anyways to keep the wheels down.
