I'd eat off of that one still. I once took off an aluminum manifold soooo nasty, it weighed about as much as a cast iron one
The car had been sitting under an Elm tree for years with no hood, and all of those little seeds had formed an inch of soil and were starting to grow little trees in it.
You know how when you clean the gutters you get that smell of rot with centepedes n crap in it.....
I just HAD to know what manifold it was being aluminum and all.......
