[Kal-EL]

Just looking at this block, it appears to be well made. The inside of the block appears to have built-in pressure as there is only a small gap between the top of the block and the copper plate. This is similar to the EK Supreme design with its pressure plate that forces the coolant to squeeze thru a tight space. The EK pressure gap is much smaller than this block but the same principal is being applied.

After running this block, it appears that the reviews are correct and this block performs on par with the EK Supreme. I like the mounting system as well but you can easily remove the existing bolt downs from the block and use it with another backplate system, no probs.
