52Carl: And that is how cheap bolts can get expensive!...:). Engine blocks are rated the same way stone is. pebbles, more that 1 in a hand. Stones, 1 for each hand. Rock, can be picked up. Everything else is a boulder. I am not picking up a block that fits into any motor vehicle any time soon. That is why I have a hoist. When I was young, and dumb, I could and I would, I ain't so young anymore. Dumb? Comes and goes. Specific weight for an inline block is exactly LOTS. My ability to pick one up, NOT.
