Ok guy I just bought a 71 truck and was running the numbers on the engine and the block that came up was 3970010 which in some places says it is a 302 block. Does this have any value. It is a std bore.

 

The 3970010 block is a common casting that was used between 1969-1972 for both the 302 Z/28 (69 only) and 350, 2 and 4 bolt mains. If your truck still has the original engine, it's certainly a 350. Odds of somebody putting a 302 from a Z/28 into your truck would be extremely slim.
Edit: your title says "69 302 block". Did you check the casting date to verify that it's a 69 block? If not then, have you checked to see if your block has matching numbers to your VIN? You need to dig a little deeper to find out what you have.

 

check the engine pad for #.. in 68 it became federal law to have partial vin stamped on the engine pad post the #'s you find

 

I'll do more research but the heads on it are 3947040 and this head was used in 68-69 and sometimes in a 302. but I'll check the stamp because it is visible
