That block is a stamped P72; so yes it's GSR, but it doesn't have GSR Block Girdle, pick up, and windage tray. Furthermore, the windage tray, pick-up, and Crank caps are LS. Also, the only way the crank will hit the oil squirter is if you put an LS crank inside of a GSR block. It looks like whoever sold you that GSR block ripped you off. I know this comment is a little late, but just in-case you're still wondering what caused the failure.
