440 block filled water jackets

They said it has main studs and been line honed, the deck trued to the crank centerline and has been grooved for o-rings. And comes with pro gram engineering main caps. That the only reason its for sale is a change in mind for the direction they are going with the build. Its been hard filled to the freeze plugs. I can definitely see 72Dart6pack where one should be cautious as it seems to good to be true. I don't know enough about blocks built like this to know what is right or good deals on them. I have never used a filled block.
