This will get it off.
To install correctly, you would need a torque wrench that will read up ~ 325 lbs. When we've done it, we've never had one handy so we've always estimated the torque. We do this by seeing how long the lever arm is on the breaker bar and the assessing the required pull based on that arm. For example, if you have a 3 foot arm, you need just about 100lbs of pull. If you have some experience, it's not too hard to estimate this how hard this is. A torque multiplier is also another tool that can solve this problem but we've never had one.
Done several front crank nuts this way, never had any problems.
