Default What Engine Do I Have?

So I bought a 1984 k10 with a sb 305 4 bolt that needs some work. The engine needs new seals and gaskets. I just decided to switch it with another 305 and get the truck on the road before winter. I noticed the back of the block was blue? Decided I should do a research on the engine and figure out exactly what I have on my hands.
Block code "3970010"
Suffix code "k03091DR" (the 1 may be a T)
Vin# "C81155096". [/B][/B]
I've gotten several different ideas on what the engine may be. Block code comes up as a Small Block V8 1969 302, 4 bolt, Camaro Z28. The vin I cant figure out because the code is out of order from decifering instructions. Best I can tell from the suffix it's from "st. Catherines, Ontario" made march, 9th. I believe the "C" in the vin stands for chevy truck. The suffix and vin are perfectly line up (suffix over the vin) and I read the only did that from 67-69 I believe. Can anyone help me decode this block?

Mine needs rebuilt, so I need to figure it out. I'm gonna have to measure the size of the cylinder. See how much it holds.

If your refering to the 4.0V6 found in the Dodge Nitro not to be confused with the Jeep straight 6, it is a solid engine. Its just a larger version of the efficient 3.5 with some extra improvements.
