The highest rating they ever delivered for the 767-200 was 60k, while 62k was available for the -300 (the 767-2C/KC-46 uses the 62k PW4000 with an available bump). IIRC the max available MTOW for the 767-200 was 380,000 lbs, but I wouldn't swear to it (the 767-2C/KC-46 is 407,000 lbs.)
I'm only familiar with the thrust I flew starting back in 1990. CF6-80C2 was 61,500 on our fleet.
Obviously your expertise goes back farther and across more carriers. I do know with the later engines on the 767-200 (60K+?) they had higher than 351K max takeoff. I think a buddy flying them said it was around 380K so our memories are similar.
