Since you are concerned with fuel economy somewhat, a turbo can help offset this and still provide very adequate HP and driveability. These blocks are very strong, and both nitrous and turbos have been used on them with great success. Tlowe is dyno testing with a turbo on the 250 dyno project going on right now, and 300 HP has already been achieved N/A, so higher HP is expected with the turbo setup. Just stay tuned in to see the results. You can PM him for more specifics if you need to.
