There is still the good ole' 4.3 liter V6....
The move to DOHC is partly driven by the countries that tax based on displacement therefore the advantages of DOHC is preferred.
As for age of the architectures..... They are all old. OHC has origins in the late 1890's, OHV debuted in the 1900's, and DOHC in the early 1910's.
