WANTED: 273 4 bbl. intake & carb.

Those CI OEM intakes are in the $250 range. They have 5/16 intake bolts on a angle. I guess you found out the streetmaster doesn't fit it.

Yes I found out the hard way. I had no idea the '64-'65 intakes were different. I've got a lead on a '65 Offy intake. Hopefully it's the right one.
