767 Inboard Ailerons (already mentioned) droop with Flap 5+.
767 Flap 1 is all Slat (no Flap)
767 Flap 30 and Flap 25 have overspeed (blowback) protection (Only on F30 with 757?)
767 at High GW has a Vref30+80 (min clean) in excess of Flap 1 Lim (250 kts)!
TOM has (had?) a pair of 762s with the -80C engines normally fitted to the 763. These 767-200Gti were a lot of fun on ferry flights, a 5000' stop height on a SID could be a problem! Automatics were way behind. Off MAN 23L you can get FL410 by BHX with pretty much normal operation (ie not hanging on the stall).
Oh, and did I mention the doors?
