Clicking off the RA4 engine, HDC was required, as was HD Safe-T-Track option. HDC consisted of the 4 core radiator, matching fan shroud, and in a non A/C only high performance application engine like the RA IV, the fan was the 5 blade factory flex fan. same deal with '68 Ram Air engines, as well as the '67 Ram Air engine.
