Installing a Tachometer?
'64 F100, stock 292 with headers and Pertronix electronic ignition.
I was wondering if there is a relatively easy way for me to buy and install a tach in my truck. I'd like to see what kind of RPM's I'm spinning at different times when I'm driving as well as for testing/calibration purposes.
Questions:
- Where/who can I buy a tachometer that will work for my application from?
- Is it difficult to install? How does it work?

You can pick a tach up at any auto parts house or through mail order.
There are 4 wires to hook up, one to ground which I believe is a black wire. One to keyed power which should be red. One to go to your light switch which should be white and the last wire goes to the negative terminal on your coil which should be a green wire.
All tachs to my knowledge come pre-set to run on V-8 engines, how ever if your reading is way off, just pull the back cover off and there is a little switch to select 4 6 or 8 cylinders.

Ford offered several tachs (6 or 8 grand) as an option on the cars of the 1960's, these can be mounted on the steering column, or the dash.
Some have been reproduced, and are available from Mustang repro parts suppliers.
The "Rally-Pacs" Mustangs had (as an option) in 1965/66 were (and are) very popular because besides a tach, it also has a clock.
These are made strictly for the steering column, are made so the gauges aren't hidden, so the tach & clock are smaller in diameter.
The way the setup was designed, the clock is on the right, the tach on the left.
There are several tachs for these Rally Pacs...one is 6 grand (used mostly on 6 bangers), t'other is 8 grand.
Ford also offered a clock that mounted to the dash.
