Does anyone know which adapter would be required for a 4.6?

 

That's a good price if someone could get it to work on the GT's.

 

I emailed the seller, they weren't much help. Said a machine specialty shop could properly make an adapter.

 

This guy is selling is stock GT500 blower for $800 here:

As for the adapter, I don't know that anyone makes one. But I do know a couple of companies make adapters to mate 4.6 intakes to a 5.4 block/heads. In this case, you'd need the opposite. In any case, hood clearance will probably be an issue because these adapters are 3/4" tall. Add the blower on top of that and.....
