408 W or 427 W?

I'm planning pn pulling my 351 W and do a major power upgrade this winter. There's magic in the "427" designation, which will match the side badges of the "427" body style. I bet the 408 W will make more power because it can probably spin faster, but all I'm looking for is a solid high torque engine: no track days or drag racing. I'm looking for previous experience with both engines, with particular emphasis on the 427 W as I know the extra .170 inches of stroke is really pushing the available cylinder space limits, especially since I have a 1970 block that is supposed to be .020" shorter on deck height.
