Personally, I'd put in a 235, but if you want to stay stock, put an ad in the swap meet and call some places around you for another block. Not too many people want the 216, so the cost of a block is somewhere at or above scrap value...

The general feeling about these was that they were actually an area of corrosion and several people cleaned them up and sealed them with J B Weld. That seemed to be a solution. | | |

Use a very hot arc but for very short distance. Overfill. after every inch, stop and release tension with a needle gun. This will last as long as original material.
