Brake Pedal Not Returning

Hi All, I have a '49 Chevy pickup with an LS1 swap. I am using a frame mounted 7" power booster and master cylinder. The vacuum for the booster is connected to the port on the on the rear of the intake manifold. The problem I am having is the brake pedal returns fine when the car is off, as soon as I start the truck and press the brake pedal it will not return all the way causing the brakes to drag. I then have to pull the pedal up with my toes. I have replaced the power booster with a new one and am having the same issue. I do have a return spring on the pedal, looking to go to a bigger one but I am thinking something else is wrong that is causing the pedal to hang. I have checked the fit between the booster push rod and master cylinder and it seems to be correct. Does the ls1 make enough manifold vacuum to operate the booster correctly?

Does any one have any ideas what might be wrong?

Thanks in advance!

-Ryan
