Not that I can detect with my "ass-dyno" (Jim's term). 

To be honest all 3 of my '77-'78 460 powered Lincolns perform nearly
identically. Because the engines themselves did not change (believe it
or not they even use the same bottom half -- pistons included -- as my
high compression 460 transplanted from a '69) torque among them is
probably as close to identical as possible, given the timing change.
Note that some primitive knock prevention features (vacuum driven)
were introduced in 1978.

The 460 was dropped from Ford's passenger car lineup in 1979 -- had
been dumbed down to the point the poor thing had nothing left to give.
Was replaced by the 400 (not a bad engine, actually). Mark V itself
was dropped in 1980.
