Since we already have a number of guys running LS1's who's gonna be the firsts for the LS2's, from what i've read the mounts are identical to the LS1.
It comes pretty much complete except for Pulley, belt, power steering pump, air conditioning pump, starter, alternator, and engine covers are not included.
