Any ideas on the value of standard bore 413 and 440 blocks? I have the opportunity to purchase a couple of 413 blocks and 5 440 blocks and am trying to get a feel for the market before I make a deal. It's going to be a negation for the lot and need to be educated before I start. He also has some 4 speeds but is not sure what they all are. I know he said a couple were 4 speed over drives.

67-72 440 blocks would be worth more to most B body guys. Racing applications will use most any block that is good. HP makes a difference too, not that it's anything more than a stamp. 413 blocks, original car blocks are worth the most to restoration guys. My guess is 100-500 depending on condition and stipulations above. Best case scenario is you find one that matches someone's pride and joy.

I would pass on the 413 blocks if you’re looking to flip them and I think the $100 to $500 range is about right according to condition and make sure that they have main caps.

For comparison I got a 1968 440 block complete pan to intake and was never apart -- scored it for $800 which was about market 2 years ago. The 440 blocks are about $300 to me as unless you can get them magged and checked they are somewhat of a gamble. the 413 blocks are probably about $100-$150 as they don't bring the same $$$ as a 440 block

A base bare 440 block...$100
With matching main caps, some more.
Add to that anything 67-72 is worth more to numbers guys
Anything 67-72hp is worth considerately more
Something like a 70hp known good could stretch $750-950.
Very regional and opportunistic since they are some trouble to ship.

Like said above, bare blocks are a gamble without being checked out by a reputable machine shop. Complete engines, never opened is the better choice if possible. Year also makes a big difference for the purist.

What would you people say a 68 Charger HP 4-speed long block, pan to intake, pulled in late 70s is valued? Never been apart.

If it's not stuck, I would say 900 maybe more.

Blocks aren't worth much until they have been checked out fully. The 413 blocks are almost worthless so I wouldn't buy those unless it has to be a package deal. 440 blocks are worth $500+ once they have been tanked, magnafluxed and sonic checked. Roughly 1/2 of the blocks available these days won't pass a sonic check so don't get your hopes too high.

Even complete engines are a gamble. Last couple of complete engines I bought were junk. It takes a few hours to pull a complete engine apart and check the block. If the block is no good then you've just wasted most of a day on a pile of scrap that all goes into the recycle bin.

That is a fair price. The crank can be sold for $100 and the block will be worth more than $500 if it checks out. It costs about $300 to hot tank, magnaflux and sonic check a block so you'll have $450 invested in it before you know if it is worth anything. Buying blocks is no way to get rich. You spend a bunch of money and time and sometimes you get the money back and sometimes you don't.

I bought it to be built. I would like to have a fresh engine for my 65

I just consider them as scrap until I can sonic check them and mag check them. Okay, maybe not scrap but cheap until I can confirm they are good or not. I usually pick them up for a couple of hundred bucks. Around here they seem to go from $500.00 to $1200.00 these days depending on the year, but I am not a numbers guy so year never matters to me. I have had 78 truck motors sonic check better than 68-70 performance blocks of that era. Hell, I just traded a 70' 383 block for a 76' 440 block because the dude wanted a 70' 383 block for his 70' Barracuda.

This was one of my better deals recently. Guy on craigslist was selling a bare 440 block for $200. Went to see him and it turns out he used to work in a machine shop and that he had stashed away some Mopar 440 blocks. The blocks were standard bore, bare, tanked and magnafluxed and he wanted $200 each just to clean out his garage. I also picked up a bare 440 block for free from a buddy who had to clean out the garage so his wife's car would fit. Of course, I have lots of bad stories to tell to about buying blocks that ended up being cracked or busted or had thin walls. Even with the good scores I barely break even on blocks.

Here is a picture from my old shop. This is back in the day when I'd buy blocks on a regular basis. They are a little harder to find these days.
