The torque-plate honing has been around awhile, so it isn't any kind of new magic mojo for engine building, but it does add alot of hands-on manual human labor that obviously adds tons to the cost of assembly, as the process to finish hone a block is time consuming requiring constant measuring and adjustment to the boring bars's stone pressures and such. I have done this work in an engine shop, and takes a skilled touch to do it carefully and correctly, try calling your local engine shop and ask them what they charge to do it, plus the costs for the machine and training of individuals to do it, on top of where do they draw the line for # of machines/employees running them to keep up with production and not slow it down. Glad to see they are adding this touch to the ZL1, but doesn't make me think any less of the LS3's.
