As always with Mother Mopar, if a car was built very early or very late in the model year when the color changed over, it is possible that an early 69 could have a red engine or a late 69 could have a Hemi orange engine.
It's not only possible for early '69 to be red, because some were. I've never seen a hemi orange engine in a 69 model year car, although there were late castings in 69 for 70 model year cars that were hemi orange.
