Here is a list of the parts that MUST be swapped from the Camaro engine to the new engine:

If you buy a FWD engine here is what you will need to remove from the new engine (and swap from your car’s original engine)
Oil Pan
Oil pickup tube/screen
Oil filter mount (on the timing cover)
Upper intake
Lower intake
Fuel rail
Fuel injectors
Belt tensioner/Heater hose manifold (replace the plastic elbows and make sure the ends of the old elbow did not stick inside the manifolds.)
Flywheel
Harmonic balancer
Valve covers (some engines have the oil filler in the middle of the cover and will not work too well with the Camaro/Firebird)
Exhaust Manifolds
Oil dipstick
All accessory brackets from the Camaro/Firebird engine over to the new engine. (You may want to leave the engine hook on the rear right side off so you can remove the valve cover easier in the future)

If you swap out these parts the new engine will look just like the one you pulled out of the car. The sensors for the Cam, Crank, and knock are the same as the Vin K engine as best as I can tell. They come up as the same part # in my part's catalog at work.
