Do you agree with this Hot Rod magazine online article quote?

I work in a machine shop, we sleeve blocks all the time. Sometimes all holes. The sleeve material is stronger than the block material, harder too. Nitrous and boosted motors keep race engine shops in business, lol. Aluminum blocks, iron blocks, CGI blocks; there's a lot of work dumped into the things to make them right before racing, you can't throw that away. And besides, many of these racers need their stuff "right now!"(often because of stupidity, cheapness and poor planning, but that's another story) so getting a new block isn't a option; if they're even available.
