A guy contacted my dad that he has a 440 and 2 400 engines for sale. What's the going price for these now a days?

The 440 is a 71 and is a complete engine (I'm assuming intake to oil pan) but needs rebuilt.

The 400 not sure of yr or if they are complete or just blocks. Mainly just interested in the value of the block since these are best built as a stroker.

I bought a few 400 blocks for $200 each. I thought that was reasonable.

For a complete carb to pan 440 I would do as much as $500 as long as it's not seized. For a bare block $250. A complete carb to pan 400 would be somewhere between those two.

Got rid of two 440's this summer. Complete top to bottom as pulled. Struggled to get $500 each. Was glad to see them gone.
Never, ever argue with an IDIOT. They will drag you to their level and then beat you with their years of experience

$1 per cubic inch assuming run of the mill non-hp engines.

67-71 HP engines could be more.

Accessories, carbs, manifolds, ect all vary the price too.
I used to care but....... things have changed

Core engines aren't worth much money since so many of them turn out to be worthless. I used to buy core engines all the time and I would have to scrap about 1 in 4 block. Once you get them all pulled apart, cleaned, magged and sonic checked you'll see what I mean.

It takes a lot of work to pull them all apart and clean them. And it cost money to get them hot tanked, magged and sonic checked. Just because of that I'm usually not interested in any big block core where the guy wants more than a few hundred bucks. This summer I bought 3 big blocks for $300 and it wasn't a great deal. One block was worthless, one didn't have main caps and one block appears to be okay. So after spending $300 plus a full day of labor and $200 for cleaning, magging and sonic checking I have a block that is worth $500.

If the 400 blocks have a casting number ending in 230 they could be worth more
