I agree 100% with Alaskan T/A. You'd need to take the sequence number off the block & match that up with the complete VIN number from a V-code car. You might get lucky with someone who does Mopar research and has huge lists of VIN numbers to match up with an original block. Having said all that, the blocks are IDENTICAL to non six pack blocks.
