I am just finishing my 216. I was able to save a great deal of money by waiting for parts to come up on Ebay. Unlike some of the other engines, there is not a great deal of demand for 216 parts, thus the Ebay offers can be quite rewarding. As recenty as a month ago there were two different offers on Ebay of the 216 crank, ground and fitted with new bearings. The original style rods are also constantly being offered.
