Engine Block Casting #'s
Can I use this to find out when the block was made? I found a block I want to buy but I am not sure if I can use roller cams with it because of the year.
The casting # is: 3970010

Very common high strength 4" bore SBC. That casting was used for 327 and 350's from 1969 to 1980. It can be 2 or 4 bolt. Pickup trucks usually have the 4 bolt block. It will use a 2 piece rear main seal.

No on the roller cam, unless you do a retrofit. You can research the engine code of any block to see it's original application. It's found on the pad in front of the passenger side head, mostly.
