I too pulled a hydroboost unit off of a Express van. All I've done is drill a hole in the firewall on the 54. I do know the master cylinder is friggin huge on them due to the equally huge calipers. I think a master cylinder from a Tahoe or Silverado will work better. I don't know what you're using it on, but you may want to make sure you have a power steering pump that has enough pressure also.
