Home built rear mounted turbo ?????

[6oneimpala]

I am considering putting a rear mounted turbo on my 63 nova, reason being that I have a 5.3 out of a 2001 Chevy Silverado, that I would like to leave as close to stock as possible except the whole 10 to 20lbs of boost thing. The reason I like the rear mounted location is ease of installation, normal headers, no intercooler ect. What all would I need as far as wastegates and componets like that to get this working. Any opinions would be nice, I really think that this would work and not cost a arm and a leg.
