Fried Liver Attack in the Scotch Gambit - Two Knights Defense? [fen ""]

1. e4 e5 2. Nf3 Nc6 3. d4 exd4 4. Bc4 Nf6 5. Ng5 d5 6. exd5 Nxd5 7. Nxf7 Kxf7 8. Qf3+ Ke6 


Now the usual move in the Fried Liver Attack is 9. Nc3 attacking the knight on d5, but the d-pawn heads this off. Is the Fried Liver Attack still viable in the Scotch Gambit/Two Knights Defense?
Given the moves in your post, the position favors White.  I think most White players would enjoy the seeing the Black King out there, suffering a pin, sitting on an open file, and flapping in the breeze on move 8 with Queens on the board.

Here's what Stockfish thinks after a reasonably long think:

...with a small advantage for White.  I see both players having a good game here.  However, I suspect Black is walking a tightrope.  That is, to maintain parity, Black must play much better than White.
