The crest is cool, but that little oil sand set core that created it also formed some other "tells" on the block. The set core wasn't specifically put there for the accommodation of the logo. It was needed to integrate the gas flow-offs in that intake rail area (which needed to be huge to accommodate the lower hydrostatic pressure in aluminum versus iron). Since it was a simple little core box, it became an easy (and cheap) place to machine in any casting plant identification. I'm looking forward to Mark's book too.

I have to apologize about the crest. The block had YENKO in block letters on the front of the block.
