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?

Are you looking at a volvo 7.4 gsi ? They are black ,rectangular intake ports and crank driven water pump .snag it .

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

But the whole setup complete, worth more than 500?
