Wanted 67-68 383 block

Its not fraud unless you are trying to pass it off for something it is not, would you say it was not right if the motor had been warrantied in 1968 and the numbers had been put on a new block? It is a factory 383 4 Speed car that has been a race car for 40 years the original block has long been blown up. It don't really matter becouse I'm not fixing it to sell and its not going back original. Just would kinda like a date code correct block to build a stroker out of.
