When I V8 swapped my Sport I needed a complete engine, conversion mounts, a dual pattern 3/4 speed bellhousing, flywheel, clutch kit, headers & exhaust, new radiator w/hoses, a custom power steering hose, fan, throttle linkage, and some odds and ends. There's not much to it.
Some stuff like the center link and crossmember, as mentioned, don't need replacing.
