The MP restoration block is a replacement 440 done from the time frame of the Crate hemi , if it's the block in my 2002 MP catolog it will be the HD casting ... hi nickel alloy water block, not siamese bore block, thicker decks, it has wedge mounting ears AND the 3 center mains are crossbolted. Stout piece. It's the same block they built the crate hemi's on so it will weigh more than a dedicated 440 block.

Can't say what it's worth , what does the seller want for it ? It probably cost over 8k to build ... depending on the head choice.
