Reply to "Reinforcing with "Hard Block""

I think that the main use has been high horsepower engines. You will sacrifice some cooling capacity as I understand it. Once the block has been filled with cementitious grout, the block or cylinder walls can't be repaired in the event of a cracked cylinder. It's popular among the Aussies and among drag racers, but would be unnecessary if the long-promised aftermarket Cleveland blocks are finally made available.
