Taking a 1965 2bbl 273 to a 4 bbl or commando settings

Hi again. When you get the input from those who really know what they're talking about ( which ain't me ) I could help out with a stock cast iron 4bbl intake manifold. The 64-65 are different from the 66-later. I had a devil of a time finding an after market intake when I had mine rebuilt.

Heck, I still have all the 100,000 miles cam, solid lifters, etc. Guess I'll make some "auto furniture".
