Just to be clear, despite all the material I've removed, this is no lightweight intake manifold. The Crosswind aluminum manifold weighs about 10 pounds as-cast, and that's with the water crossover attached. The Edelbrock Performer weighs 15 pounds as-cast. The HO reproduction weighs 8 pounds as-cast. My endless hours of grinding on this cast iron manifold resulted in a 27 pound part, without a water crossover. It's still VERY hefty and VERY stout, even if it's significantly lighter than it used to be. I'm guessing porting will remove another pound or so.
