As
Dave has pointed out once a 340 always a 340, despite incorporation of mod -144. See note seven of the attached TCDS link which says,
Model 340 airplanes, S/N 2 through 311, are eligible for operation at Model 440 weights
and performance limitations as shown in the Model 440 FAA Approved Airplane Flight Manual when the modifications outlined in Convair Service Bulletin 340-144 have been incorporated
