Hard Blok for 340 Stroker

I got a 360 block filled to a little under the water pump holes when viewed with each deck horizontal. It was a bit much because I have to closely watch and time the water temp so it doesn't get too warm when I get to the lanes and the starting line. Oil get's hot quick too. I can tell by the oil pressure. I had my next engine done with less, but don't recall the exact measurement. But even a 1/2 fill is suppose to be helpful and should make an obvious difference in controlling water and oil temps over what I did.
