I do not know the engine bay size for a 67. I put a 351C in a 65 Falcon with the stock 289 motor mounts. However, there was no room at the shock towers. I have been told that Crites Restoration motor mounts raise the 351C engine approximately 1 inch, thereby increasing space at the shock towers. Crites is good about answering questions on the telephone. I also had to use an old "big six" L adapter to turn the oil filter down instead of out.
