The Shelby block is 118 pounds, The Iron Side oiler block is 255. That is a137 pound diff. Parham is way way off. I also have a 351 Winston cup iron block and it is 205 pounds. The RDI (Ford Racing ) alum. 351 block is 115. pounds. The iron sideoiler is certainly heavier than the 351 iron block. These are factual #'s not something dreamed up.
