I would be leary chuzie with the grade 8 you have 13,806lbs double shear which has a safety factor of 1.7 for 8000lbs winch. Now if you use a snatch block back to the vehicle you basically double your pull strength to 16000lbs which will have a safety factor of .86 so it will most likely break. FYI when I deal with stuff I like safety factors between 4 and 5.
