the 07 classic should be the same as the 06 but I'm not a 100% on that as I'm a midsize guy

Correct me if I'm wrong. But I have never seen an nbs truck with dod.

If it has dod it will not work without moving the knock sensors and using a lingefelter 58x 4x converter module to make the newer motor talk to your older pcm. You also have to lengthen the cam sensor harness wires and run them to the front timing cover

The 07.5 up motors that have DOD use a 58x crank sensor and 4x cam sensor

Just to clear things up...you have an 07 classic with a 4.3 and you want to put a 5.3 out of a 07.5 nnbs? Am I understanding that correctly?
