Welcome, Steve,

FWIW, the OEM P/N 2x4 Rochester carburetors are very rare and very expensive.

For $300-400 each, a professional carb shop, such as Daytona or Nowlan's Carburetor & Ignition, 433 E Sprague Ave, Spokane, WA 99202, (509) 624-8524, can rebuild a pair of regular Rochesters to nearly the same specifications for you.

Then, you'll have to fabricate the linkage, lines, shields and air cleaner.

If you don't care about looking original, just use a pair of Carter/Edelbrock 1405 500 CFM carbs and aftermarket air cleaners. IIRC, the reproduction early Corvette 2x4 can be used.
