Intermediate shaft question

I just received my 71 360 short block from the machine shop. The machinist recommend i try an intermediate shaft in the new bronze bushing before I start assembling. I plan on running a stock oil pump. What shaft do I need? I was thinking this would work? http://www.summitracing.com/parts/mel-is-72/overview/ I do not have a cam yet but plan on running a mild cam. Also wondering what to run for an oil pump. Car will be street only. This will be my first engine build, so any help is appreciated.
