Tachometer- Needed on automatics?
Hey guys i'm restoring my 71 and im gonna order and install new gauges from auto meter and make a custom instrument cluster. I dont want to spend 200+ buck on a tach I don't need and never look at when im driving. I could understand if it was a manual car, then the tach would be useful. what are you thoughts? Needed or not needed on a automatic 71 Olds 350?

Automatic or manual trans is irrelevant. A tach provides information about the engine the same as a water temp gauge or oil pressure gauge. I can't imagine driving a car without one.
And there is no need to spend 200+ on a tach when you can get one for $40.

I have a column mounted tach in my 54. It is Stewart Warner Wings series which looks correct for the car. My speedometer is about 8 mph slow so I know at 3,000 RPM's I am going about 70 mph (see what 3:36 gears and no overdrive will do). For the most part I really don't need it but I just think it looks cool.

Many people think the tach is not needed on an automatic, but is for a manual, but ignore the fact that you usually shift with your ear and routine muscle motions and hardly ever look at the tach while driving a manual normally.
My priorities: Oil gauge or light....speedometer....temp gauge or light....fuel gauge....tach....voltmeter.....oil temp....transmission temp....I guess a clock
They make nice little 4 in 1 pods that do fuel, temp, oil, and volts. I'd do it, a custom tach, and a speedo. You can look at your phone for the time.

Here's the tachometer I've had for nearly 20 years. It's not in my 71 98 but I guess I should install it (it's just sitting in a box in the garage). I had it installed in a 1990 Buick Estate Wagon and the 1964 Olds 98 I owned.

This is why I had the tachometer installed in my Estate Wagon. The speedometer didn't work because the drive gear in the 2004R was worn. Instead of pulling the tail housing and replacing the drive gear I just used the tach.
