I'm sure Aeromotive make one that can handle that without breaking a sweat, but by the time you spend Aeromotive money on a regulator like that, you've already spent enough to swap in a proper in-line fuel pump and sump the factory tank (or even swap it for an '85 style tank that's already sumped).
Me personally, I wouldn't run the EFI pump with a carb under ANY circumstances. You can run a bypass regulator and then run an additional regulator after that between it and the carb, and I still wouldn't feel safe. It's just not worth the risk of burning my car to the ground. I run a mechanical pump on my car (like it had from the factory, only a 90gph Holley) and it feeds my 347 just fine. I like the idea of being able to swap out my fuel pump in 10 minutes with a factory replacement if my Holley ever croaked and left me stranded.
