G.M.C. used dozens of different carburetors on different year and application 228 engines. ALL that I have information on are ZENITH size 10 and 11.
Zenith had intermediate sizes; but both the Zenith size 10 and size 11 correspond to an S.A.E. size 2 flange which is 2 11/16 center to center.
The throttle bore on the Zenith size 11 is slightly larger than the Zenith size 10; again BOTH are 2 11/16 center to center.
The Zenith corresponding to S.A.E. size 3 would be Zenith size 12.
If you have a good G.M.C. 228 Zenith carb, perhaps you could find a Chevrolet 216 intake and use the Zenith carb.

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 | | |
