On the front of the motor, passenger side, the block deck extends past the cylinder head. GM stamps this part with a block suffix code and a partial VIN number. Post these numbers for further decoding. Note, if your block has been decked, these numbers may be gone. The 3970010 can be either 2 or 4 bolt main, but all are 4" bore. It is a good block and fairly common. In the bellhousing area as well as under the timing cover will be some 2 digit numbers as well, either 10 and 10 or 10 and 20. These are in reference to the amount of tin (1%) or nickel content (1% or 2%,10 or 20) The 20 blocks are high nickel content blocks and are most desirable for wear resistance).

Heads: 14014416 This cylinder head is about as good as a Bow Tie Late Model Stock head because the chambers are so tight and the ports offer decent flow. They also have a good, thick deck so you can cut them down a bit. For a stock cast-iron head, they are hard to beat. Camel Hump
