really really really heavy. if you did use it as an anchore i think you could hold a submarine in place. Over the holiday i took it down to the machine shop. and being the clever little midget that i am, didnt ask for help unlaoding it got the thing out of the truck bed, was trying to get it to the ground, useing my upper leg to support it, and then! dun dun dun!!!! my knee gave out, ankel twisted, and that heavy p.o.s. fell on my calf.
on the plus side, i usually have chicken legs, with all the swelling, it looks like i have a muscle

 

that sounds like it hurt

 

lucky it was a 6.5 block and not a 5.9 cummins block

 

They are not that heavy.

 

It sucks but funny hope you get better.

 

I did not feel it
