Lift 440 fully dressed +trans with this?

Thousands of people use those, the thought of all that weight being held up by 4 little tiny 7/16ths bolts threaded into old cast iron or alum. threads just creeps me out LOL, so personally I wouldnt use one but all those other people trump my one personal opinion.
I use a chain unless the trans is comming out too then I have the fancy leveler thingy.
