408 W2 combo - where to from here

750hp Holley >> 850 mechanical secondary. (750 might be a bit small considering the rest of the combo)
3.45 diff gears >> 4.10's (if not highway driven, will improve 1/4 times drastically)
find a way cut some weight from the chassis.
run it without full exhaust when you run it at the track.

just a few ideas for some gains.
