If I understand correctly, the 28 intake is different then the earlier ones. How do I tell the difference? Is it the ID of the tubes?
Thanks

as far as I know they are the same as prior years short drop the check valve might be different
I have a 1927 Chevy Capital AA 4 Door also a 1927 Chevy Touring car, a 1936 Chevy 1/2 ton and a 2010 Corvette LT3 Convertible and a 1953 Packard Caribbean. My tow car is a 2011 Suburban.

The inside diameter of the 1928 was larger. In 28 they went to larger valves and I think that the carb was larger also. The inside of the manifold is 1" up thru 1927 and then 1 1/8" for the 28. If the manifolds are on an engine the outside of the tubes will measure about 1 1/8' for the early ones and 1 3/16" for the 28.

From the info above, if it has the 2 port exhaust then it would or should have the larger valves and intake. If I read the date code on my head right it's Nov. of 27 with duel exhaust and larger valves.
I thought the intake was larger but was not sure, thank you. This will be a help.
