The moter is completly apart. I cam measure anything. The pistons are stamped 390 but the tag on the intake said 360. Can I determine the engine size by measuring the pistons, rods, ect? The crank has no numbers on it so I can't run the numbers.
The stroke is the only real way to determine the displacemt of an FE. And that's actually easier with the rotating assembly installed. You might be able to look at and measure the stroke on the cylinder wall...maybe theres a clear ridge at the top and some indication at the bottom of the cylinder of the bottom of the stroke.
The rods should have a part number as well, which might help determine if they were 360 or 390 rods. I assume by the pistons being marked 390, that they are the standard 4.05" bore, but you could measure that as well. Usually they are marked with an overbore if that was done...
itll be hard, but like scouder said, look at the cylinder walls and try to see if you can see the where the pistion has been going, then measure the top ridge and bottom ridge and thats your stroke.

What, now Scouder and me are they same guy?
You'd think on a running motor there would be some visible sign on the cylinder wall showing the stroke, from the rings.
