Could Edelbrock cast a flathead block

[rotorwrench]

Good question! Their blocks were different but not different enough to be a problem. If a person could get the core molds and box, they would have most of the work done. The core molds that were different could be changed to get rid of the lump on the back of the block and improve the intake runners. There is a good probability that they were scrapped but you never know.
