Why do we not see many large displacement FI engines?

I have always wondered on this. ITs pretty easy to make a +460 CI engine using the LXS blocks. They are certainly strong enough to open up this big and some even up to 500 CI with the tall deck version.

Why is it that we do not see any large displacement engines used with a blower setup up for even mild boost?

I would think a 460-480 CI engine with 6-7 lbs of boost would be scary powerful.

Do we not have any blowers that can keep up with the volumn needed for this size of displacement.

Just curious why its not done. I was reading up about an LSX build that was 500 CI that produced 717 HP and around 650 Ft/LBs of torque and thought, wonder what 6 lbs of boost would do to those numbers.

Certainly am not an expert, maybe there is a very important reason why we do not see this from a mechanical set up reasoning. Just curious and would like to be educated by those that know.
