Guys that buy Cobras want something extreme. You don't *need* anything nearly that fast. These cars would be fast with iron blocks or even SBCs. But if you're gonna build or buy something that's totally extreme, you might as well do all the little things that add up, and that make it a fun project. An Al block and saving 125# fall into that category. For me it was a difference of maybe $500-600. The only thing that would give me pause if I were to do it again is that the pan on this engine has never sealed well, despite some pretty extreme measures. I think it would be better with an iron block. But it's a relatively small issue.
