What can I expect it to run?

If hp figures right and you hook I would say mid 9's easy. Let me know how it works for you as this is roughly the setup I want to replace the b block I have when I sell/ blow it up. Only difference I wanna go with the 4.2l blower and turn the wick up alot more.

4.2 is huge.. challengers running arounf with my same setup running 18 lbs are ETing 9.50 in a 4400 lbs car... that's pretty damn fast. lol Take 1000 off that spin it to what ever we want, we have superior suspension and your in the 8's!
