It is nothing like the crappy manual drum systems we all remember from back in our younger days.
I usually build and run engines in my street cars that are not friendly with vacuum assisted brakes. Camshafts with large .050 duration numbers and tight LSA's generally don't make enough vacuum for a vacuum assisted system to work very well. You end up with a very hard pedal and poor performance.
Lastly, while hydraboost systems work great in any application, I don't care for how they look and how much real estate they take up.

Thank you for the explanation. I think I will go with manual as well. Sounds like 7/8" bore is the ticket.
