I used a 454 Mag MPI setup on a 540 that made 567hp. That was with a ASM ported intake and adjustable fuel regulator. It ran out of air on the dyno, so I expect that is about the end of it naturally aspirated.

It looks so similar to the 525 efi blue intake. Are any parts the same?

Not the same as the 525. Not even close if you have the 2 side by side comparing
