Looks like a 250 to me.  The 292 side covers are taller.

Definitely a 250 cause of the short lifter covers and cause the 292 has the passenger side motor mount and fuel pump reversed!

If it is supposed to be original, it would be a 250, a 292 wasn't offered in half ton.

can you comment on this?  Is this for later years?  My '68 C10 originally came with a 292!

Now it has a really expensive 292 with all of the expensive Clifford goodies!!!

Yes, in 1979 292 engines were not offered in C-10's only the heavier light duty trucks had them.

Definitely a 250.  The 292's didn't have the emmisions (humps on the heads)
