I have a friend who is putting a 427FE in his 68 convertible. If there a motor mount out there that will lower the engine more than others? He is about an inch to 1 1/2" high for the hood. He has a cobra supersnake  replica with functional dual superchargers.  He is planning to do same matching engine setup on mustang. He was looking into customizing hood , but wanted to minimize bulge in hood by lowering engine. I think the total control and Ron Morris mounts only give you 1/2"-1" drop I believe. He may be into fabrication,  just like the rest of car. 600+ hp is a lot to ask of an old car. I had other friends build a 66 gt350 for a dr.,  who had them put in a pumped out 427 tunnel port engine. After the good doctor stabbed it hard, the rear frame mounts where they are welded to the floor pans/back seat footwear area, actually tore out of the bottom of the car and springing the trunk upward some. So any ideas are greatly appreciated.  Should be a neat car when done.
