WANTED: 273 4 bbl. intake & carb.

I'm trying to turn my '65 Barracuda into a Formula S clone.. At the moment it has the 273 2 bbl. I'm looking for the factory OE cast iron '64-'65 4 barrel intake and hopefully the factory carb. that fits it. Would be willing to trade an Edelbrock 318 Streetmaster with a Carter afb 9636 carb. for them.
