Need with power brake booster

I just put a holley street avenger on my 71 cheyenne and my brake pedal is now hard as a rock. I thought maybe the booster went bad so i pulled one off my big block parts truck that i now was good i drove it two weeks ago and the pedal is still hard. I even put a plastic tee off the other side of carb and no luck. I dont know what else to do, could it be something with carb being a bigger carb or what. Any help would be appreciated.
