Can we get an idea of when your car was completed at NJ? This is often important when we get to details. Thanks
Found this thread focusing on the air cleaner. Note that the pictures include examples that have been repainted so don't use them as a guide for those purposes
https://www.concoursmustang.com/forum/index.php?topic=15808.msg99029#msg99029Don't remember if there is an example in the Unrestored Picture Thread but easy for you to check

Here is a start try to get some information posted to help out
Engine would be painted as usual. Long block with valve covers, intake, spacer, carb (bagged) oil pan w/plug, timing cover, oil filter (already painted did not get fully painted in the painting of the engine , thermostat housing, bypass hose and clamps, water pump, exhaust manifolds, engine plate (thin steel plate between the engine and transmission, flywheel as well as almost all attaching hardware Ford Corporate Blue. Exhaust manifolds were typically not fully painted and typically left a paint shadow behind them on the upper engine block and valve cover gaskets and not all retaining bolts were installed before painting the engine.
Think that is all of the items but may have skipped over something
Harmonic balancer, coil, Pulleys -Semi-gloss black
Coil bracket would have been P&O

As far as examples I suggest you seek out original unrestored examples rather than restored ones since just about all will have something finished wrong or out of place. Just happens The vast majority of the details on a non-Sport Sprint will apply to your car so don't turn a blind eye those that resource and opportunities. Also consider that all of the details one the engine as shipped (no air cleaner, most hoses and such are all the same no matter where the car was built since they all came from the same engine plant for your engine size
A decent example of a almost complete engine can be found by searching for - 17,000,000 Engine at Cleveland Engine Plant
Will post, hopefully, more than a half dozen pictures that should help.
