previous owner dropped a 2.8L and 5 speed into my 260.

is there any way to determine whether these were pulled from a 2+2 or a coupe?

If its out of a 2+2 it will have a 240mm flywheel. The 280Z coupe had the 220mm.

Problem is: getting a look at it without removing the transmission.

so there's no way of telling one from the other without pulling the transmission? crap.

Its the only difference I know and when its in a 260Z all the external stuff is swap over from the original L26.

The L28 came out in March 75 and stayed upto 1983 when they changed to the 300ZX.

There are two block models; the N42 (March 75 to mid 1980) and the F54 (mid 1980 to end 1983)

The non turbo had three different heads. N42 upto mid 1977, N47 upto September 1980 and the P79 went until the end of the 280ZX.

That might give you a clue as to "when".

the "what" is an n42 block, n47 head, and a 5 speed.

but i'm trying to sort out issues with a new clutch. so the question of the day is "which". 2+2, or coupe?

not sure if "when" is a factor.
