Jerry M has an interesting explanation in his book.Apparantly although the fan blade design is identical on the Z/28, L72 and L78, there are technical differances. The Z/28 and the BB cars got both the stamped and unstamped fans, Technically speaking, both fan assemblies would be correct for 302, 396, and 427 solid lifter engines.

That's not what it says.
&quot;The L78/COPO used part number 3946050 (stamped CZ) and the Z28 used 3946804 (stamped CV), both Eaton-supplied units.&quot;
