1969 Camaro ZL-1 #51

[GRB]

When Reggie originally bought the car from Walden for a reported $250k (a lot of money at that time) wouldn't Reggie have been informed that Walden still had the ORIGINAL block? The ruined (?) supposed ORIGINAL block would have been worth far more to Reggie than Walden. Does it make sense that a savvy buyer like Reggie would not have gotten the old ORIGINAL block for $250k???

Is it even conceivable that the GM rep. would have knocked the serial number off the block rather than return it to GM who would have far more interest in the failed block than the ser. no.???
