I am a very similar case. My height is 5'10 and I weigh 165 lbs (75kg).
You can find all the world records here, tested and untested.
This guy Kjell Egill Bakkelund holds it with 716lbs (325kg) @165 lbs.
You can see him doing 320kg for 5 in this video.
You can find a few guys here and there pulling over 700 at this weight such as Paul Nguyen (717@165 and 740@167) BUT, you will notice that these guys are shorter than you. This considerably shortens the range of motion and makes it easier for them to pull.
At 5'10 and 160-165 lbs, you and I are probably not likely to go for world records, at least not in this weight class.
However I do believe 600 at our height and weight is achievable.
I pulled 315 a little over two years ago. I can now pull 500 without a belt or straps. And I'm still seeing progress and definitely think 600 is achievable.
One important thing to consider is genetics. Some people progress faster and further. The majority will never pull 700 at such bodyweights. But 600 seems achievable for most young people.
Less than 3 years is possible too. Your programming, eating habits, sleep and overall stress levels are the biggest factors. A big thing is do not get injured because this will harm your progress and set you off for some time. Slow and steady. Form first.
Also your age will impact a lot. I assume you are in your 20's so this shouldn't be a problem.
Best of luck !
