I have a neighbor that has an old 440 replacement block still with original tags on it that has never been built. It has been kept oiled down and wrapped in storage, looks in great condition.

I am considering a mild 440 build and the price on this block is cheap... Am I saving myself machine work here or should I still expect more work than just a hone for reasons that I'm missing?

run a dial bore gauge thru the cylinders and measure them. chances are your good to go as is but i'd check anyway.

you'll need some sort of machining...at the least some honing..but I would wager a shop will want a slight bore and hone of course

Sorry Mike, just the one, but I'll give you first dibs if I don't end up using it for my build.

Well,I very much doubt the factory used a torque plate when it was machined....

Probably a +/- range, narrow, at stock bore. Main thing you should look for is if, over the time the block sat, it changed shape any. That just means check each bore for roundness. Don't think the factory would let something much out-of-round to hit the door.

Otherwise, it's either good to go, or needs a quick hit on the bores.

Good for a mild build. Not so good for a high hp build. Not til its been 'seasoned' by heat cycles and has settled down.
