Finally installed a 4K rpm tachometer.
What a revelation! Now I know a lot more about what's going on with my engine. I can't remember the last vehicle I owned that didn't have one but I've been driving this 40 more than 20 years without one. At tune-up time I have always hooked up a temporary tach and vacuum gauge in the engine bay.
I mounted it to the steering column support under the dash as I didn't want it strapped to the column in front of the cluster. It's not like i need to monitor it every second like a drag racer. It looks kinda cramped but there really is a lot of safety room. I have flopped seat brackets and sit pretty far back so there are no interference issues even with snow boots. My view is like this...
The tach is an Autometer 2890 Z-series. It's all I need as the cam in this engine is pretty much dead at 3200rpm. I don't think it'll ever see more than 3500. If it does I've got bigger problems than a clapped out gauge. I ran the more brightly colored wires through a short section of black shrink tubing to cut down on the visual clutter but somehow forgot to include the white dash light wire. I can live with it. No way am I de-routing that wire back out of the light switch plug just for aesthetics. If it bothers me I've got a Sharpie at the ready.
