I wouldnt trust a factory tacho as far as I could throw it.
I once built an engine that should have been okay to 8000.
It refused to go past about 7600 no matter how much I ignored it's screams for mercy.
The next engine I fitted an aftermarket #OOPS# light. When I was showing 7500, the stock tacho was only ready 6200.
it was then I learned factory datsun Gauges were to be taken with a grain of salt..........
