Quick Autometer voltmeter wiring question..

I'm installing a series of gauges below the radio, one of them being a voltmeter. Autometer instructions state to run a 12V switched source as well as a "good engine ground."

Is an "engine ground" really necessary? I would think running the ground to the chassis (ie; the steel dash reinforcement) would be acceptable? Is there any reason an actual engine ground would be necessary?

Now with a 9.5:1 Coyote Aluminator and t56 Magnum looking for a little boost....
