Back in the day (late 80s early 90s) I frequented a yard in Cicero IL. I could by 350s all day long for $100.00. They were guarnteed to not be busted inside if they were we could bring them back for exchange. When I asked him what he did with all the engines he pulled (he had them pilled up all over) he told me he sent them by container ship to Australia the used them for racing?? I guess he was selling them by the #.
