I want to make an old style clamp on barrel 880 with a smooth bore barrel, an old style clamp on barrel 880 with a new rifled barrel. Is this just a matter of drilling a transfer port hole and the little flat that is in front of that? Am I oversimplifying it?
Why? What is restricting it's power?

What is restricting it's power?Daisy has done much playing around with the chamber volume inside the valve body.The new valves have more volume...until the seal abutment is installed...the nose takes up way more volume than the old style seal..However, the 1977 abutment has a hollow abutment nose, but the greater swept volume of the pump gives mote psi per stroke.Larger chamber volume builds less psi per given # of pump strokes.Smaller volume builds more pressure but has less air to push the pellet upon firing.I believe that to be responsible for the difference is "pop" when you pull the trigger...higher pressure makes a sharper crack..I suspect that setup gives higher pellet speed as well.....Don't mind me...I'm arguing with myself.....
I'm wondering if there are different abutment washers for the 1977. You have mentioned hollow abutments in reference to the 1977 multiple times but I have yet to see one out of 4.

That would not be necessary with a solid abutment nose....
