That's always been the plan! The new block (also a D0AE) is at the machine shop awaiting boring. Half-fill of Hard Blok is already done and the block is cleaned up.

Two stickers installed on the Scion xA (my daily driver) a little while ago, will report on how they hold up.

What is the reason for filling the block with Hard blok, would this not cause the engine to over heat lacking in cooling? I know that only half the block if filled, but that is half the cooling as well.

The fill is for strengthening the cylinders, Cleveland's are one of the first thin-wall casting technology blocks.

Half the cooling? One might think that but read on. Most of the heat is in the top of the cylinder where the combustion takes place. My current block is filled the same way and cools just fine in 100 degree heat with the AC running! I do use a brass four core radiator though.
