[K5owner]

This is true as I can attest to it. These engines are assembled in Mexico from new cores but who is pouring the cores and doing the machining I don't know. However, it doesn't seem to effect function though as everyone I have talked to who has had one said that they ran great and were very durable. I know when my 84 K5's 350 gives up the ghost I probably will replace it with a good wrench replacement. Solid 4 bolt main engines with good value.
