I installed a "new" GM crate engine twenty years ago in my K1500. It worked out OK.
The price of GMs new engines is now double what it was then.
At this point, I'd head to a Treasure Yard, find a used engine in adequate-to-good condition, and either run it as-is, or rebuild the thing myself with the help of a "local" machine shop.
Bore wear on used engines used to be horrible. Now it's hardly noticeable. The "used" engine option is relatively safe now. A "hundred-thousand mile" used engine still has a hundred-thousand miles left in it. Maybe more.
That gives you several options, among them slapping in a Treasure-Yard engine as a semi-permanent fix; installing a Treasure Yard engine as a temporary fix while you "hot-rod" your original engine, or hot-rodding the Treasure Yard engine as you limp along with your current engine.
The really nice thing about GM "new" crate engines is the warranty.
