Just a follow up in case anyone was wondering.

New is nice, but it's nicer when it's cheap. I'm into this entire set up so far for about $375 including the intake, the carb, all the linkage pieces, brackets & gaskets to do it. Now I just need to find the time to actually swap it all.

I will hold onto the stock, cast iron intake for now since I still have another 318-2V engine kicking around in my Coronet convertible that one day may get redone.
