I am not sure Steve, The block is not at my residence..I work shift work and am on shift right now. I thought I got all the numbers but I will look again and get back to you, it might take me a couple of days. As far as price goes...not really sure yet. Do you have a 66 that the numbers will match?by sonta - Pontiac GTO Forum
cast # on the block is - D 9778789 production date code is - C186 as far as the heads go, not sure if they are original or not found a stamp that reads 0092 The block is located in upstate New York in between Albany and Saratoga Springs. It was running when we took it out but had a good knock...it definately needs to be rebuilt and it does not have the original carbirator. Let me know if you havby sonta - Pontiac GTO Forum
