Paul, to fill my clevelands I use Moroso block filler. It comes in four one gallon bottles. One bottle will fill one side up to the water pump outlet with a little leftover.

Clevelands have fairly thin cyinder walls and they are prone to cracking when making lots of power. Heavy pistons, high compression, and fairly high rpm's are hard on the thin cylinders. So by filling the block, it stregthens the cylinders from the backside and doens't allow them to flex which causes cracks.I hope I am right, since that is what I have always believed.

That and the filler keeps the bores tight and straight so as the pistons do not deflect at high RPM. :0------------------
