Doing some of my airplane learning, I have come across a point many times that the engines for the Boeing 747 (at least partially) came from Boeing's competitor to the C-5 Galaxy. What was this plane that Boeing had made to compete with the C-5?

I'm not getting this question, the C-5 is military and the 747 is civilian. Closest thing is the C-17 GlobeMaster III I think. – Ron Beyer May 17 '16 at 00:42

@RonBeyer I am asking about Boeing's competitor for the C-5 contract before the C-5 was. It is just like the YF-23 was the competitor to the now F-22. – SMS von der Tann May 17 '16 at 00:45

1According to the book The C-5A Scandal the 747 came out of Boeing's failed bid for the C-5 contract. – radarbob May 19 '16 at 04:30

In 1964 the US Air Force awarded study contracts for a new cargo aircraft to Boeing, Douglas and Lockheed. The aircraft was called CX-HLS. ( cargo experimental - heavy logistics system)
Lockheed won with the C-5A design. Boeing's design was never built but would have looked like this:

1Based on the TDPRI link, it appears that Boeing called theirs the "C-X", which seems pretty darn generic... – FreeMan May 17 '16 at 12:21

Boeing called the aircraft CX-HLS( Cargo Experimental - Heavy Logistics System). It never entered production though.
The below image is of a scaled down model of the CX-HLS.
