Think this intake swap will hurt performance?

Well I painted the M1 tonight so I'll install it tomorrow. I should be able to come back with results after tnt on Friday. I need to get it ready to run because I'm running at Mopars at the Motorplex on Saturday and another series I run on Sunday. I can handle it slowing down, a little, I just hope I don't lose the consistency.


Do you think I outta reuse the 1/2" open spacer?
