hey guys. bought a 2000 malibu vlx this weekend only to find the block cracked from water being frozen in the block. the motor still runs and sounds good and has only 216 hours on it. any ideas. i would have no problem pulling the motor and swapping over parts (say if i got a short block.) is that my best option? and if so where would i find one? does it have to be a marine block or will just any 350 vortec work? any help would be appreciated in need.
