Shifting

[Buickforlife]

What is a good shift point for a stock GN? I just installed a monster tach, and it shows it is shifting right around 3000 rpm. Can I take it any higher than that and still be safe?

Thanks

It could be that and make sure ur tach is set on 6 cylinder..My autometer is a smaller one and i had to cut a wire (per the instructions ) for it to read correctly for a v6..Im not sure on the monster tachs they may have a switch... Mine shifted at 5000 1-2 and like 3300 on the 2-3 when in drive i went 14.50s shifting at 5000 manually i went 14.42 and 14.55 shifting at 4500 i went 14.22 wheelhopping

I completely forgot about that part. I bet it is still set for 8 cylander

I'd say 4500-4600 rps, since the stock setup (cam) stops marking power at 4600 r's
