Ok, so I checked out the 350 by hand cranking it with the intake manifold, and valve covers removed. Everything looked fine and dandy, so I think I am ready to put it back together. It came with a Rochester Quadrajet, but it's definitely in need of a rebuild. Is this carb worth rebuilding? Or should I buck up and buy a shiny new one? I've never heard of Rochester before, but that doesn't mean much at all. Thanks for the help in advance.
