If you did that I would use them.

Call any manufacturer of them and they should tell you not to use them in this way. Just hit them or apply pressure (in any orientation) and they MAY fracture. They may not, but if even one falls with a car (or a piano) that is too many.

I agreed with Ed and tried to use some humor to make a point. Sorry if you didn?t take it as such. Go ahead and use blocks to your hearts content, but it MAY fracture, and over time with enough repeated stress probably will. Wood blocks won?t, ever. No personal slam to you Jeff.
