Is this particular tach any good?

Paul my man remember why your putting the gauges in there..the REAL reason. All that money on that fine motor, you need to know what's really going on. I would get nothing but autometer IMO..tach if you choose, but without a doubt you need water and oil in place before you fire her up for the first time. My tach is not for show (honestly it's a little too much for my taste) but my stocker is litterally a thousand RPM off after 4000. When my stocker reads 6000 I'm actaully only coming up on 5000!!!
 
and thanks for that link stangGT, i think i may get that one, cuz i like it, and it's an autometer, so it looks decent (not a big fan of huge tachs either but) and it's an accurate autometer
