I got a call from the original owner (his son) that I bought my 68 350 from. He is claiming to have found what he believes was the original motor (short block) to my car in their barn. If true its been there since 1971 and is very corroded! Anyhow its in a very difficult location (fell through floorboards) to get at so I cannot see the VIN stamping or castings without a real commitment and half a day. I can see the stamping on the front surface near the water pump which 8C4Y. My car was built 4/23/68. I certainly hope it is the block, but before I commit my time digging it out and I suspect a lot of $$, I want to be sure based on these numbers it seems right. Thoughts?
