I wonder if there is a quick and inexpensive way to temporarily rig up a tach, so I can check engine rpm at highway speed.

Pretty simple, just lay the tach on the front seat and run the leads thru the air vent to the engine compartment. That's how I did the final check on my Ultramatic to confirm it was slipping after lockup when applying heavy throttle.
