Hotrod Lincoln was correct in my case; I had my 216 rebuilt and insert bearings cut in to it. I got it home, rebuilt the body when I got the parts back from the paint shop and when I got it started there was an 8 inch crack in the left front side of the block in the water jacket about 2 years after I had it rebuilt so I really didn't have a good argument against the rebuilder asking him to correct work he did 2 years earlier. I contemplated welding and JB weld also, doing a Google search I found Lock N' Stitch in Turlock California that sells stitching pins and has tech support to help you all along the way. Peggy has a Tech Tip pending when she gets time to post it as I took pics along the way. The pins actually pull the cast into the pins instead of inserting the pins and them pushing the crack outward. They are very forgiving and you can drill into a neighboring pin and countersink it and run a tap into it and insert the next pin. I can send you a copy of the tech tip in word format with pictures imbedded, Flicker wouldn't let me up load a word document if you need or want to see it before Peggy gets enough time to post it. Good Luck and it can be done. Mine was less than $250. But I got a little to aggressive with a smaller pin and it stripped, so I had to buy 25 of the one size larger pins and that mistake cost me another $100. My mistake and I needed to slow down. After view looks like the crack never existed and it doesn't leak anymore at all. You can also ship the block, bell housing, head, or what other part you want to them and they will repair it for you. The also offer mobile service, I know their website shows a cruise ship repair that threw a rod and they replaced a large segment of the side of the block using that process. Regards, John
