Block casting number only tells use the very basics of what it is....."3970010" is a 4.00" bore block , used to make the '69 Large journal 327" and the '68-80 350"....

To know the actual application we need you to post the stamped numbers on the flat pad, facing up, just forward of tha passenger side cylinder head and just above where the passenger side water pump leg bolts up to the block.

It should follow this format....a letter, followed by 4 numbers, followed by 2 or 3 number digits.
Example : "V0218CKM"

V = Flint Engine Plant
0218 = Date code, in month/day format, so "0218" is Feb(02) 18th day(18)
CKM = Application suffix code, "CKM" is 1976 350, auto trans, 170 hp, 4 barrel, from Camaro, Chevelle, Impala/Caprice, or Nova

There may be two number strings stamped on that pad....if there is, the other set is a partial vIN from the original car it was installed in.....but not all blocks got a VIN stamp.

Yes, thats the correct pad....but all we can see is the VIN string.
Thick paint, painted over rust and crud may be obscuring the Application suffix string....or it may have rusted enough to nearly eliminate them....or it may have been a service replacement warrantee/crate engine and never had an application suffix.

Try sanding or wire brushing the pad down to bare metal to see if the second code string will show itself.
