How long can the truck be out of service? An engine rebuild could easily take a month or more when you factor in proper block and cylinder head machining.

It could also end up costing more than this new GM crate engine.

Make no mistake, this isn't a high performance engine, but with a small 4 bbl, headers, and proper ignition curve it's great for a pickup, especially one with 3.08 or higher (lower numerically) gears. And if you're so inclined you can install a slightly bigger cam for more mid range punch. I say "slightly" because its low compression does not lend itself well to cams that close the intake valve much later than the stock cam.

If you can afford more, here's a good choice, but it will need an intake manifold that will fit Vortec heads.
