Concrete they have been doing forever, but it's actually cement with either very small or no pea gravel, sometimes glass fiber. If the oil is hot, doesn't mean the block is much above ambient, particularly if it's dry sumped, common also because there isnt recip parts sloshing in the oil reservoir and you can plumb it to deliver oil even inverted, which as I recall, bad juju on a drag strip.
