I asked the GOOGLE and this is what it said....

3970010 is the block casting #. That # you listed was used on all of chevys 4.000"
bore engines

Look on the right cylinder block in from of the head. There's a machined surface and the engine codes should there if the block has not been milled. Should be 2 set of characters, one it the engine code and the other the VIN derivative. Look something like the following.

T1024TFD engine code
If the first letter in the suffix is the letter T, its a truck engine. C its a car engine.

hope that helps cheers
