Extra Engine

[etg]

Hey all, a neighbor of mine has a c20 just like mine but in better condition. A couple of months ago his engine seized up and he had to park it. He got another 350 block in it and decided to give me the old block. I took it because I want to learn how to dismantle it and learn all the inner workings first hand, without destroying my own 350 block. I was just wondering what kind of info I could figure out from the numbers on the block. Any input helps.

Here's what's stamped on the block:
GM 3970010
15k106215
v1018crx

Intake manifold:
3927183

In between the valve springs:
333882


So my plan is to just take it all apart and eventually sell it or get it machined and sell it. Is this engine common?

the 3970010 block is the high nickel one used in Corvettes, trucks, and boat engines. Good block, usually but not always 4 bolt.
