If the magnum engines are anything like the older 5.2's then yes there
is a bypass hose from the water pump to the intake. You should have one
heater hose from the intake and one from the water pump. The heater hose
fitting from your old intake should work in the new one as they are
usually a standard size

The deal is the power brake booster uses engine vacuum to assist you
with the brakes. It basically has a rubber diaphragm housed inside that
big cylinder and the vacuum created on the front side from the engine
helps to pull the brake pedal down allowing you to use a lot less
pressure to apply the brakes

You could drill a hole for a fitting to run the brake booster in one of
the intake runners. this should work as long as the booster is in good
shape, if the booster fails it will create a miss in the engine, as the
engine will draw air from the booster and not the T.B. also recommend if
you do this to add a one way valve between the engine and the booster
similar to what G.M uses on their early 80's vehicles to keep vacuum
built up in the booster so you don't have a miss at start
up. Do Not run the PCV from a intake
runner or you will have a miss, because as you open the throttle vacuum
drops and the PCV opens causing a vacuum leak to that cylinder, I know
this from personal experience I had on my old 360 with a torker intake
which was drilled for a fitting in the intake runner from edlbrock
As for air flow restrictions if you tap into a intake runner just cut
the fitting off so that when it is installed it is flush with the with
the inside of the runner.
Hope this helps
