Just to the bottom of the freeze plugs will help a little, but if it's not a circle track or street deal, I'd fill it to the bottom of the water pump holes. You should do it before the sleeve install or at least before the final bore....

i run a 388 sbc also with the block filled to the bottom of the water pump inlet i run a meziere eletric pump and no t stat, i cant get my motor to run above 160 i use my motor alot on the street and its 15.5:1 compression. if i do let the temp run up 180-90 not using the fan, it does take longer to get the temp down back around 160. most of the time i usualy dont use the fan she just runs 160 cruising around. hope this helps your decision.

zerotolerance where do yo u drive this car? In alaska? Antarctica? Theres no way you can drive a block filled 15to1 motor around and never worry about over heating unless it was in a boat getting 20 degree water for cooling. lol... Im curious.
