i would find out if the motor is stuck first, does it have anything bent or twisted on the frame? look the engine over good make sure you don't see any cracks in the block. see if it looks like it was greased pretty good- most of the time if it is covered in grease it was mostly likely taken care of somewhat. if it all checks out i would guess like crenwelge about the 1,000. range maybe 1200.
