Re: 3.4L and 3.4L doch

The 3.4 DOHC motor was designed to make 275 HP and was detuned to 200-215 because GM didn't have a FWD trans at the time that could take that much power. They can rev up to 7k RPM but were programmed to shift at only 6250. Maintenance is key, they're belt-driven cams and it is labor-intensive (and expensive) to replace these, hope you don't ever break one because you can bend the valves.
