Depends on what exactly you are getting. My guide shows
15.9-18.75 Same engine (used) INCLUDES R & R OF COMPLETE ENGINE (WITH MANIFOLDS - COOLING & ELECTRICAL SYSTEMS INTACT)

22.3-23.5 For a long block & transfer parts. INCLUDES R & R OF MANIFOLDS AND ALL NECESSARY GASKETS - TIMING COVER - OIL PAN - CLUTCH - AND NEEDED ADJUSTMENTS ---NOTE--- IF YOU ARE NOT REPLACING GASKETS YOU SHOULD USE LABOR DESCRIPTION --> R & R ENGINE & TRANSFER PARTS

27.2-28.6 for short block & transfer parts. INCLUDES - R & R OF COMPLETE SHORT BLOCK ASSEMBLY - - - HOSES & BELTS - FUEL ASSEMBLIES - ELECTRICAL COMPONETS TUNE ENGINE AND MAKE ALL NECESSARY ADJUSTMENTS.

I have found this guide to be pretty accurate for most things.
