Local guy has a 350 bare block, casting number 3970010. I was told it is a 1971 4 bolt main. It has never been bored over. Guy might be interested in selling it, but I have not asked pointedly yet. Just curious, what would this be worth, or what is a good offer? I want to rebuild the engine in my K10, but want to be able to use it when needed, so I was going to buy a separate block.

Just a block with nothing else? $50 in my opinion if you can trust it is good.
If we lived a bit closer I would give you a block. It would cost you more than $50 to come get it though. ;D

yeah chevy 350 blocks are cheap... you can find them anywhere... just make sure itīs all in standard measurements and it isnīt cracked or anything

Agreed a bare 350 block and you're taking his word for it? Look carefully at the cylinder walls and the main bearing bore. Measure as well.
-
No way to guarantee the block isn't cracked without paying for it be magnafluxed. But I guess all used blocks are a gamble to a certain degree.
Thirsty, you are in NH right?
-
other thing is are the mains marked, or were they kept in order?
In my opinion if you are looking for a motor to rebuild get one that runs good, just tired, or smokes. That way you are 99.9% sure it won't yield a big suprise when you go to make it fresh again.

Yes

Alright, well I will keep my eyes peeled for a better engine, hopefully one I can get dirt cheap.

So if I am looking for an engine that takes roller lifters, that is only the 87 and newer engines right? I understood that basically if it has a one-piece rear main, then the engine has a hydraulic roller cam, is that right?
-
One piece rear main seal began in 1986. The 1987 up would be a one piece rear main seal, but it may or may not actually have had a roller cam installed or even machined for a factory roller cam. Also, some of the early one-piece blocks may not have been drilled for using an engine driven fuel pump.

LT-1 or Vortec blocks will have what you're looking for
