Depends on what year engine's your going from and to and if bolt /engine surface locations are same, lots of variables.

Unless you find the parts locally, you'll pay a lot. They seem to be sold/offered on ebay for a premium, usually. Also, the AC compressor might not bolt in since GM switched designs along the way. Then there's location. GM switched sides with the compressor and alternator.

If it's a work truck, why change it?

Pull off your old set up, not that many bolts/ nuts to remove. GM probably took the easy route and had the serp setup bracket's fit existing bracket locations, rather than redesign the block.

Well...they did redesign the block when they went from Mark IV to Gen 5, and then again for Gen 6.

But the various bolt hole locations may be the same.

As the blocks he said he has are close in manufactured year, it would be worth trying; not saying that changes don't happen.
