Concrete blocks are "dicey" and cinder blocks a no-no. If using

A cinder block can disintegrate with little provocation and no
warning.

Excellent point. They can crumble pretty easily if they have an internal
flaw and you've positioned the block precisely the wrong way. I'd never put
a car up on cinder blocks, especially *stacked* blocks.

I've had sheet metal stands buckle on me, leaving me pinned under a 2 ton
Jaguar Mark X. My mother, who noticed I was no longer making noise, came
out to the garage, saw me pinned under the car and lifted it off me. She
was 4'10" and under 100 pounds. Amazing what adrenaline can do. (Of
course, the full weight of the car wasn't on me since only one of the 4
stands had failed, but it was enough weight across my chest that I couldn't
free myself). Working on cars was never quite the same for me after that
even though I went out and bought a hydraulic jack and expensive, well-made
jack stands. Two minutes of thinking "I am going to DIE here under this
lousy car" while struggling to breathe seems like an eternity.
