[YENKO DEUCE REGISTRY]

I understand that Don would have done anything to get rid of the orig. L78's, whether they be complete engines or just the short's from the '68's.

Any '69 427 Nova that is claimed to be a COPO would have to have serious paperwork in order to be believable, not impossible but highly unlikely. Not all of the '69 Yenko Novas were 427's, supposedly, approx. 7 were left as 396's with possibly a supertune. That is similar to the '68 Harrell Novas, you could get them plain Gibb style, Harrell L78 supertuned, or Harrell L?? converted.
