123 Puzzle: rpm change after 4-speed install

I just completed (well, still waiting for a shift boot actually) a manual conversion on my wagon. Things are ducky. I love it.

But... everyone else here has said they had no change in final drive rpms. I am reading 3000 rpm at 75; with the slush drive it was 3500 at 70. The needles used to be parallel on the highway. Now 60 mph looks in 2000-2500 rpms.

New speedo cable (old 240 style, my trans is from a 79) same rearend, same instrument cluster.

California car, not that I think that means anything.

Any ideas???
