You know, I learned stick on a car without tach. Nor did the car I had after that one. It's funny but it wasn't till the late mid late 80s or 90s that cars started to regularly have tachs when, in all irony, the shift in favor of automatics was in full swing. What is the pint of having a tach with an auto trans?
I remember the 78 Surban we had. The instrument cluster had two big areas. One was the speedo. The other seemed like a natural for tach, but no, it was...a fuel gauge. For a 30 or so gallon tank. It only used a a small portion of the area. Now it is true, with a 454 cu-in engine and a 4 bbl carb, if one hit the fuel hard enough you could literally watch that fuel guage move as the engine swallowed fuel at some incredible rate.
