sluggish 280 engine follow up

I posted this problem on 6/21 and got a suggestion of bad vacuum advance or vacuum leaks or bad cat converter.

Here is how i am circumventing the problem.

When the car hits 55mph (which is about all it can muster) I set the cruise control
and then lift up on the cruise control lever. The car responds and smartly speeds up to whatever speed I choose without downshifting . As long as the cruise is on the car has plenty of power.

Any thoughts on how this can be?

Thanks

Dan
