I posted the HP and Torque for the 86 on one of the other threads under here. It seems it was 226 HP and 365 ft-lbs torque. I don't remember the RPM, but I found it under my Mitchell on Demand, it's not in the owners manual. Keep in mind the EPA really killed bigger engines, particularly the ones with any kind of quench area. That's why the brand C stuff is even more gutless.

The numbers you posting, 210/365 were pretty accurate for the carburted engines. My 1977 Lincoln with the 460 is rated at 208hp/356tq. The replacement engine that I got for it is a 460 from a 1989 F-450, and it is rated at 220hp/390tq. Through the 90s, there were minor horsepower and torque improvements, mostly when they switched to the F3TE cylinder heads, which have a better swirl pattern, in I think 1993.
Most of the power increase came with the switch in 1989 to tuned-port fuel injection and the myrid of computer controls that came with it, along with the fuel-injected cylinder head design with, from what i've been told, is much better then any of the previous carbureted heads in terms of flow.
