I found a 6.0L and 4l80E Pullout (harness, computer, accessories) out of a 2004 Chevy Van. What is a reasonable dollar amount for this?

Are there any bad things about getting a pullout out of a Van? (reduced compression, HP, etc) Is this what I should be looking for in a 6.0L? I know that it isn't a LQ9, But I am not sure what it actually is.

Any input, or wisdom would be appreciated!!
