These values from the official Field Service Manuals for Rams indicate that camshaft lifts did change from 1992 to 1993:

But the FSM are not completely free of errors.
I know the 1995 Ram FSM has the wrong drawing, weights and specs for the Magnum 5.9 piston.

5.9 "Advertised" 1994-1997 and 1998-2001 cam specs

In the above link for the 5.9 cams i wonder if the year columns should be reversed?
The 1998 and above cam was supposed to be more duration and +15 HP at higher rpm.
