Need help on motor ID - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I recently purchased a 68 K10 and am not sure of the motor I have. The PO thinks its a 350. I was told 350's were not available in the 68 model year.

The casting # on the block is 3970010 and found the in 68 that # was on the 327. Also that this # is on the 350. I am confused.

Can anybody tell me if I have a 327 or 350. Or what is the easiest or best way to tell which it is. IE: What #'s to look for and what those #'s are for each block.

Thanks in advance.
