Got the MKII out for a drive to town and back yesterday (60+ mi) and
as I was coming home, I realized that everyone was doing well under
the speed limit(according to my speedo) where they usually are doing
~5 mph over. Going up the canyon, my speedo said that we were doing 35
mph, but I was turning 3000 R's in 4th gear!. On a short stint on the
highway, I was running 55mph at 4500 R's.

The diff is a 4.22:1, but I had to replace the trans last year with a
used one- its a ribcase with an 1100G laygear in it. It just doesn't
feel right,like I'm running a speedo gear for a 4.88 diff. Any
thoughts? The tach is a repro electronic with VDO internals and a
Smiths face, so I'm pretty sure its acurate.

Since you have a Mk II with a 4.22 gear, that is correct for the car.
The laygear would not have anything to do with it... Have you replaced
the speedo? As far as the tach goes, most after market tachs have a
switch on them for the number of cylinders. Is it set for a 4 cylinder
engine? Does the engine sound corrolate to the reading on the tach?
