Anybody converted their brakes to power brakes, while still running a stock flathead? Just curious if there is sufficient vacuum pressure and does the original intake have a good port for the booster. FYI.....original 51 Mercury flathead with original intake and carb, just as it came from the factory in 51.
it should work, as long as your Flatmotor pulls 15" vacuum or more. Add a vacuum reserve tank between the manifold and booster. 4TTRUK
