There is a lot of differences between the gnerations. LB&/LLY are closer together then say LLY/LB7 to the LBZ/LMM's but in no way could any transplant/engine swap be considered cheap hp.

Between different ECM's, some bellhousings, tranny cooler lines, 5 (lb7/lly) and 6 (lbz/lmm) speed ally's, different injectors, wiring harnesses and a load of other things im forgetting to mention. It would be an expensive swap unless you had an entire doner and wanted to make the retrofit work.

IMO the different stock generations to me are different levels of strength and durability. "Cheap" HP is easy to find in any duramax, making it reliable is expensive.
