Since my block has a vin already stamped then it obviously came from another car. Any other possibilities? But it's a good idea. My car WAS Palladium Silver, but was painted T/A white long ago and has 38,000 showing. Cool car anyway.
The pic attached is from the PHS documents. It only shows a highlighted '350 with a YE block'. There is nothing in my packet that shows proof or some cross-reference that my VIN# matches this block type. The only solid info i recieved was the dealer order form. It was a customer special order sent to a dealership in Oregon.
