Twin J57 would be big, and early (by mid 1950s Grumman was looking at J67/J75/J79 for Model 110 for instance).

F-101 used twin J57.

But the engines were not J57s, rather J79s...

Could you be more specific? A fighter? naval design? which requirement?

Pratt & Whitney J57

It was the engine of choice for many OS-130 contenders, all of it single engined designs.
