 Where do you draw the line at modern engines in old vehicles, in particular V6 diesels and automatic transmissions in Shermans?  There is a shop in France that ditches the WW2 powerplants for much more fuel efficient and reliable engine and transmission combos.  Out of highway buses I think.  The exterior is the same, but not the sound or the innards.
