Think this intake swap will hurt performance?

I've taken the first step in my turbo swap and sourced a Mopar M1 single plane intake (what a pita to find for a magnum btw), and will be installing it this week. To be honest I'm not too worried about losing a little hp/tq since I bracket race mostly, but I am curious what you guys think. Current setup is running an Edelbrock Air-Gap w/ 1/2" open spacer, 9:1 360 magnum, 216/224 .506/.506 114, 850 dp, and I shift at ~5500. A run from last friday:

R/T: .015
60: 1.624
330: 4.805
660: 7.519
MPH: 90.21
1000: 9.871
1/4: 11.860
MPH: 112.46

Care to make any predictions? Do you think my carb settings will change much?
