Rather than answer in individual threads, I decided to open a new thread. Please check the following link to my articles page: http://www.thecarburetorshop.com/Zenithsizebreakdown.htmAnd this link also may be useful: http://www.thecarburetorshop.com/Zenithcodebreakdown.htmJon.
Good carburetion is fuelish hot airThe most expensive carburetor is the wrong one you attempt to modify. If you truly believe "one size fits all," try walking a mile in your spouse's shoes!The Carburetor Shop | | | | | Joined: Nov 2002 Posts: 2,766 Carburetion specialist | | Carburetion specialist Joined: Nov 2002 Posts: 2,766 | This thread was basically a response to a question about the G.M.C. 270. If you check this link: http://www.thecarburetorshop.com/TruckkitsG.htm#TkitGMCYou will find G.M.C. used Zenith 28AV11, 28AV12, 28BV11, 28BV12. And Zenith made the 28AV12 WITH DIFFERENT INTERNAL VENTURI SIZES for engines from 245 CID to 525 CID. To determine the airflow, one MUST do more research than just the carburetor type. Jon.
