Page 54 of the 2007 Rulebook, defines the currently operative criteria for carburetor use. Reference the sentence that defines the use or replacement carburetors. The blueprint page lists the carb venuri/throttlebore sizes for eligible Quadrajet carburetors under footnote 7, (1375x2250/1093xAV). There are many Quadrajet numbers that were made with these sizes. For example, compare the sizes listed for the 255 horsepower, 350, with those listed for the 325 horsepower, 396. Compare these numbers with the sizes listed for other years. You'll find that there are many numbers that are legal for use in Quadrajet applications in Stock or Super Stock Eliminator.
Price? Typically, you get what you pay for. Contact several sources and make a choice: Dean Oliver, Danny Ashley, Val Hedworth, and many others sell prepared Quadrajets.
