The maggie is not going to be able to feed a 408 effectively. If you go with a mild cam, ie 02+ ZO6 cam, the 550ish rwhp range should be pretty easy to hit. The nice thing with the maggie and 408, you will have a metric **** load of low end torque.

112 will barley make another 50hp on a decent N/A 408. I have seen one or two that would make 525 to the tires w/o the blower and see them make 575 with the blower at 8psi. I look forward to more on the 2300 with the bigger engines though. Seems like they are making about 700whp on the Zr1's at near full tilt.
