There should be a sticker on the valve cover indicating the engine type (if it's still there and ligible). If not, start by how many cylinders it has (6 or 8). If it's 8, count the valve cover bolts.
You can also enter the vin number on this site: http://www.medicine.wisc.edu/~mrm/bronco/ftvin.cgi and it'll tell you all kinds of stuff including the original engine.
Try searching this forum for more information on engine identification. It's been discussed numerous times.

Start with the number of valve cover bolts.
If it has 8,this means it's either a 351M or a 400 ?
To tell the difference between these 2 you will have to physically measure the stroke as externally they are identical.

There are a couple of ways.
One is with a rope, the other with a piece of doweling.
With the dowel located in the sparkplug hole into the cylinder ....You basically turn the engine over so the piston goes to the bottom of its travel.
Make a mark on the dowel for lowest point or BDC.
Now turn the engine over so the piston comes to TDC ...mark the dowel.
The difference between the 2 marks is the length of stroke.
4" stroke = 400
3.5?" stroke is a 351M
Maybe Bubba here explains it better.

584 is probably the engine size.
As I said in the other thread, That is plant reference info.
Which valve cover and where on it did you find it ?

That's the engine calibration code sticker to let you know the values of any tuneup specs and to also explain the proper vacuum hose routing.
It should look like the pic top left hand corner of this page.
