I don't mean to be discouraging, and I think it's definitely not impossible, but I certainly wouldn't expect it. Everyone has a different LSAT ceiling IMO, although study and preparation definitely help. I started practicing a long time ago, and my first few cold tests were apprx. mid-150s. I just scored a 166 in December 2009, but that was after a very long period (years on and off) of study and many practice tests (some of it is just the luck of the draw I think, as I did hit the 170 mark in practices occasionally, but also would score low 160s not infrequently). Go for it, and you just may do it, but I think that any sort of expectation that this will happen (especially given your short prep time) is most likely unrealistic IMO.
Regarding the second poster who stated they got a 163: I personally think that taking the practices is the best form of studying, as long as you do go back and review your wrong answers. I think if your 163 was at the top end of your practice test scores (or above) then it may be unlikely that you will gain much on a retake. However, 8 practice tests isn't a whole lot, so perhaps you can hit 170 with intensive study before the Feb. test. There are so many variables that influence actual performance and consequent score that it is hard to predict what is really possible (though it is fun to try!). Best of luck if you do retake in Feb.!
I had some practice tests in the high 160 range and one at 171.  My low was a 159 and a few were between 163 and 166.  Total, without checking, I'm pretty sure it went something like 161, 163, 159, 165, 162, 167, 171, 169.  I wasn't too disappointed in my score since it fell with in my PT avg range.  I was OK with it.  However, I did completely duff the games section so I am kind of burdened with the knowledge that I can do better.  
I started studying last night using the suggested method.  It will be more difficult.  It will be particularly cumbersome analyzing my reading comp sections.
Thanks for the advice and encouragement.
