Most parts made for 2007-2010s will fit your sled. Some minor changes and revisions were made almost every year, particularly in the front end, up to the '09s, but most of the aftermarket stuff will work for all of them. When searching for parts, the most common classification will be "2007-2010 Polaris IQ", or something of that nature.

Not at all! The original Liberty 700 was a smallblock, its base form used from 1998-2004. The 2005-2006 700 is based on the big block 900 bottem end, quite different but not really in a good way. The new (and last) small block 700 came along in 2007, and after some minor mapping revisions in 2008 it was a really a great, solid motor.
