in CL. I talked to the owner and says it's his fathers. He's selling it for him. His claim is that it's from a '67. I have a '67 with a '68 GM replacement block. I would like to have the original but it looks like the engine was decked and the stamps are gone. Is there any other way to tell what this motor came from and if it's from my car? http://boston.craigslist.org/nos/cto/1647302816.html
About the best you can do, if the block has the right casting number for a 67 big block vette, is to use the C2 birthday calculator to determine when your car was built, and compare that to the casting date on the engine block, to see if the engine block is within the acceptable range for what your car would have had.
Even then, all you can do is determine that the block couldn't possibly work for your car, or it simply may fit with various degrees of uncertainty.
