If it has a VIN stamped in the side of it starting with 5R09K then it MIGHT be an engine which originally came in a GT350. The C5AE-6015 was a generic 289 engine block..used in everything from lower powered C code cars all the way up to K Code cars. Have you verified that it is, in fact, a HiPo block or are you just assuming that because of a C5AE casting number?
Regardless, I think it is unlikely to be a GT350 block with a 4H date code. JMHO
