416 stroker cam choice

lots of good info so it looks like im going to dump the 416, i see the duration is a lot shorter and the center line is numerically bigger what does the centerline do and will the roller cam give me a lumpy idle ? on the 5.9 how much potential do i have with the stock bore and not breaking the bank i know heads,cam, headers, 52mm tb and a tune. 3000-3500.00 will get me close to the 400hp mark?
