Will I have room?

[Red 409 63 impala]

I have a 63 Impala and wondering if I will be able to fit all of this in the engine compartment. If I use the high performance exhaust manifolds can I install them with the engine installed in the car, or be better off installing them while the engine is out of the car. Engine is a 409-425 hp.
I have been told I will need a special bracket for the power brake booster if I add power front disc brakes. Also any known problems adding a power steering pump. Thank you.

If you install the engine, without a tranny, it's more or less, straight down to the frame. With the transmission, hanging down, it will be more difficult. Putting the manifolds on, after the engine is in, is easy, coming up, from the bottom.
