I also found out that the only engines available for the short-hood (93" BBC) H/J 90 series in 1970 were the Detroit Diesel 6-71 and the Cummins NH 230.

In 1971, a tilting hood was made available for the short-nose models, and thus the Detroit Diesel 8V71 and the Cummins NHC 250, previously only available for the long-nose (C/M 90 series) models, were also available for the short-nose models.

Additionally, the Cummins-powered models were given two designations: the HN/CN (4x2) and JN/MN (6x4) models were given NH-230 engines; while the HC/CC (4x2) and JC/MC (6x4) models had the "Custom Torque" NHC-250 models.
