Matt, I think they were playing around with the long nozzle early, so if you remember it that way, no doubt you are right. I think they went to the long nozzle on them all because BV wanted it that way (maybe cause it took the hot gasses further down the Bandit bypass?).

K1, you gotta remember that when you speak of a "750", that covers a lot of different engines. The early 750s & 750Fs were totally different engines than the 750Ps (750 Plus). The Ps were detuned 1000s that had different compressor wheels, diffusers, shafts, mods to the bearing lube system (to try and stop the rear bearings from saying "see ya"), etc. from the old 750 & 750F.
