You can use either cyl. 1 or cyl. 4. Cylinders 1 & 4 are at TDC at the same time, one on the compression stroke & one on the exhaust stroke.
Ford probably says cyl. 4 for the E-type because it's probably easier to get to in a van...
You would have 7.3 engines if they were new in 92. The F series 7.3 has a pulse adapter to time it on the #1 injector line. If they used #4 to time an E series I would think the pulse adapter would be on #4.
As I was reading through, I was thinking about that pulse timing adaptor as well, as I believe (at least as far as injector lines go) #1 and #4 are the only ones that are different. IDIdieseljohn may be able to shed more light to some more differences too.
Assuming use of aftermarket timing device (Ferret), I would actually use the #4 line on the F-series engine and the #1 line on the E-series - reason is that these lines do NOT have the factory timing adapter, and so they are more like the other 6 injector lines, thus reading off these lines will give a more accurate picture of when the rest of the injectors are firing. Actually I seem to recall someone on OBN using the Ferret device on both #1 and #4 lines on an F-series engine, and the #1 readings were less consistent than those taken at the #4 line with no factory adapter on it.
Obviously if a factory Rotunda timing device will be used, then hook it up to the line with the factory adapter on it, #1 on the F-series and #4 on the E-series engine.
The other guys pretty much answered the timing question.
As for telling a van engine from a truck,
A van engine will have the fuel filter on the driver side of of the engine, and F-series have it on the passenger side.
Best way to tell 'em apart after a swap.
Another way is the driver side exhaust manifold, witch actually looks like a manifold, unlike on the F-series where it flips up before comming down to clear the cross member.
Also the oil fiter.
On and F series, the oil filter leand to the front.
On an E series, the oil filter leans to the back.
That is comparing from top to bottom.
